12 EXIT TO SYSTEM Note that throughout this users guide, the actual text shown for your computer may vary from that listed above. This is due to changes made necessary by the number of lines and columns available on each computer. For example, on the apple using 40 column screens, the above text has had to be severely shortened to permit the text to fit on the screen.

Option 1) DISPLAY FILES ON DISK - To see what files are already on the disk, respond to the question WHICH DRIVE? It is, normally best to put only one set of data on a blank disk, thereby leaving a maximum of room for the wave equation to put answers on the same disk. We normally label the disk with the client's name and job ID, and after running the wave equation, file the disk with the other job information for future reference. If you have several other files on the disk, be sure that you have enough room for answers to be written on the disk - use STAT or CHKDSK or whatever your computer uses to determine how much room is left on the disk.

Option 2) DELETE A FILE FROM DISK - To delete an unwanted file from the disk, simply answer the prompts as they appear. Be sure to copy any good files onto another disK before deleting them from the present disk or they Will be lost.

Option 3) RENAME A FILE ON DISK - This option is used to rename an existing file on the disk to some new name.

Option 4) COPY A FILE - This option is used to make a backup copy of an existing file either using a new name on the disk, or putting a copy of the file on another disk.

Option 5) LOAD A FILE FROM DISK - If you have previously built a data set on the disk and wish to either check or modify the data, use this option. You will be asked which drive the data set is on, and then what name the data set has. For example, if the data set has the name JUNK.DAT, you should respond only with the name JUNK since the program asks for the three letter extension separately. Thus you would respond with JUNK and hit return, then respond with DAT and hit return when asked for the extension. If you change your mind after getting into Option 5, and do not wish to load a file after all, simply hit RETURN instead of giving the file name.

Option 6) EDIT PRESENT FILE - If you wish to make changes to an existing data file, use Option 6. Note that you MUST have previously built the data file you intend to edit, and that you MUST have loaded it into memory before it can be edited. Thus, you must have used Option 9 (discussion follows) to first build the data file and save it on disk, then use Option 5 to load that data file from the disk back into memory where you can then use Option 6 to edit it.

Thus the general procedure is as follows:

a) Use Option 9 to build the data set and load it on disk. If the data set is ready to run, run it using MICROWAVE.

b) Should any changes in the original data set be desired, use Option 5 to load the data set from disk back into memory.

c) Use Option 6 to make any desired changes in the data set. Note that once the data set is loaded into memory and modified, it need not be saved under the same name unless you so desire.

You may bring in the data set with the name JUNK.DAT and modify it into a new data set without losing the old data set JUNK.DAT. Simply give it a new name when you save the data set.

Option 7) CHECK PRESENT FILE - Option 7 is used to check a data set which has been loaded from disk and modified. Note that Option 7 is not needed the first time a data set is constructed and saved on disk. In this case, the data set is automatically checked and saved. Option 7 is useful when you have previously built a data set and wish to modify it into a different although similar set of data. Also, if you make a mistake when building the original data set, but cannot get back to correct the mistake, do not abandon it and start over. Simply finish and save the data set, then load it again using Option 5, then correct your mistake using Option 6, then check it using Option 7, and finally, save it using Option 8.

Option 8) SAVE PRESENT FILE - Option 8 is used to save any files which have been loaded from disk and modified. It is not used when the data file is initially built, since those files are automatically checked and saved.

Option 9) BUILD A NEW DATA FILE - Option 9 is the first option used, when running the wave equation. It is the basic means by which data files are built. The other options will probably be used more often, since many data files are simply modifications of previous runs. However, a truly brand new data set must be built using Option 9.

Option 10) MERGE TWO OR MORE DATA FILES - Option 10 is used to combine two or more data sets to be run at the same time. Note that when you run several data sets at once, you obviously need more space on the data disk to store the answers. Thus you need to be more careful as to how much blank space there is on the data disk for answers. A second consideration is that the data editor (Option 6 and the data checker (Option 7) can only be used on a single set of data. Thus if you wish to merge three or four data sets together to all be run at once, you can do so, but you cannot then modify the data sets, nor can you check them. This is really not much of a restriction, since the data sets must have been checked before you could save them originally.





However, to prevent merged data sets from accidently being loaded and then erroneously edited or checked, they are forcibly given the three letter extension MRG. Thus, if you say you want to get three separate files, and merge them under a new name called STUFF, the file will actually end up with the name STUFF.MRG and you must use this name whenever you want to run the data in MICROWAVE.

Option 11) PRINT A FILE - If you wish to see the final input data set you have generated, as required for input to the wave equation, you can use Option 11. Note that the format will appear similar (though not identical) to sample problem data sets appearing in the user's manual. The most obvious changes will be the addition of card numbers at the end of each card, as required by MICROWAVE. These card numbers are generated by EDITWAVE - you need not enter them.

Also, some widening of the data fields was done to improve the capabilities of the program.

Option 12) EXIT TO SYSTEM - When you are through either generating, loading, modifying, or merging data files and are ready to run them, you then exit back to the operating system, out of the EDITWAVE program, and run the MICROWAVE program. Be sure to save your data before exiting to the system or you will lose it.

MICROWAVE

To run data sets previously generated by EDITWAVE, put the program disk marked MICROWAVE in Drive A:, and the data disk in Drive B:. On some computers it will be necessary to hit Control C to boot in the drives. On computers with a hard disk, you can simply copy everything off of the distribution disks onto the hard disk and run your problems from there.

Once the disks have been loaded and "booted in", type either MW88 (if your computer has no high-speed math co-processor) or MW87 (if you have a co-processor.) If you do not know if your computer has a math co-processor, try running MW87 first, and if it runs, you have one and the runs will go much faster. If you get an error stating something like "no co-processor found", then use MW88 as your program.

After you invoke the program with either MW88 or MW87, you will be asked to give the name of the data set to be run. Give a complete description of the data set name, including the path, if necessary. Be sure to use the three letter extension MRG if the data to be run is a merged data set. You will also be asked if you wish to save all of the answers in a single answer file, including both the stress results and the blow count summary, as well as the force-time results, or if you wish to split the stress/blow count summaries and force-time results into two files.

To further explain this option, look at one of the sample problem output tables. Note that the output consists of a summary of the input data, then a summary of the force-time values which occurred during the hammer blow, then a summary of the maximum tensile and compressive forces (or stresses) and the blow count observed under one hammer blow. Although the force-time values are often of interest, they are not usually desired in a final report, and must often be cut out, or the stress/blow count summary must be retyped into the final report. By allowing the user to put the force-time results in one file for inspection, while putting the report summary values in a second file, this problem is overcome.

Assume for example that you are going to run a data set named JUNK.MRG. If you decide to place both the force-time answers and the summary answers in a single file, the answers will be placed in a file named JUNK.ANS which stands for ANSWERS. However, if you run this same data set and request that the answers be placed in separate files, your summary answers will be placed on the disk under the name JUNK.ANS and the force-time answers will be placed on the disk under the name JUNK.LNG, where LNG is an abbreviation for LONG. In any case, you can get a printout of either of the files using EDITWAVE, Option 12.

If you would like to preview the answers on the screen, you may use any normal word processor, or you may use your computer's version of "TYPE". For example, assuming that you are currently on drive A (the default drive is A), and your answers are on drive B. To view the summary file, type: TYPE B:JUNK.ANS |MORE To view the long file (force vs. time summary) you would type: TYPE B:JUNK.LNG |MORE

Sample Computer Session

The following cases present an typical session with the computer. The program disk EDITWAVE was in Drive A:, and a blank formatted disk was in Drive B:. The disks had been booted in using Control C, and the prompt A was shown on the screen. The items which should be typed in by the user have been enclosed by the symbols [ ] --- to distinguish them from the text generated by the computer. In each case the ENTER key was pressed after the given keystrokes were made. Do not type the [ ] --- symbols, only what is inside plus the ENTER key. In the case where only the ENTER key is pressed (i.e. no data is to be input), the symbol [CR for carriage return is shown. Note that all of the options on the main menu were utilized, but only to show how they work. {Notes in braces are comments and discussion about the data being entered.} A [EDITWAVE] --- {This means type EDITWAVE and the ENTER key} Editwave/Readwave 9.12 23-May-94 Copyright (c) 1994 Pile Dynamics, Inc.
