A Strange Error (COBOL)
Hey all, got one mountain of a problem here. I have completed a program I had to do for college homework, but when I run it the output shows almost nothing it is suppose to. This only happens when I RUN it though. If I hold F11 to STEP through the whole thing it shows the results as it is suppose to be. Normally I would not ask about something this big but I am stumped. Here is my code:

To me it seems that the logic is right as it does work, but for some reason it (in my mind when i see the results) jumps completely over 520-WRITE-FILE when it runs. With this I do leave a few notes.
I know 510-TABLE-SEARCH makes little sense and I intend to change it later, but I need to fix this first and it works for the moment. Unless it is the main problem please don't harass me over it.
I will be willing to add the data in the SEQ files if someone asks me for it.
My code might be a bit complex and I admit to that, but I am doing the best I can with the teacher I have (I mostly have to learn this stuff on my own).
I appreciate any help I receive and thank anyone who tries to help in advance.
edit: I am using a compiler called Micro Focus, Net Express 5.1 Academic Edition and my OS is Windows Vista. As for what the program does show when I run it, it just shows my two heading lines and then my totals-line without anything but the first field showing. I hope that helps.
I don't know for certain if this is the problem, but I can see a logic flow that isn't going to work very well...
First: 400-SALESMAN-NAME reads salesmen records from a file into working storage table SALESMAN-TABLE.
The file probably looks something like:
01Sales Guy One
02Lance Winslow
03Scott Peterson
04Willy Loman
When the read loop is done, SALESMAN-NUMBER will equal the table index because of
the way you load the table (using SM-NUMBER-IN to set the table subscript). No problem so far...
Next: 500-PROCESS-FILE loops through all rows in the SALESMAN-TABLE by running subscript ROUTINE-CHECK from 1 to 99 and performing 510-TABLE-SEARCH to write out the report for the salesman where the subscript equals SALESMAN-NUMBER...
Next: The SEARCH statement. This is where it all goes strange and never performs 520-WRITE-FILE.
This is why.
The SEARCH statement implements a linear search (SEARCH ALL is a binary search). SEARCH just increments the index associated with the searched table and then runs through a bunch of WHEN tests until one of them "fires" or the index runs off the end of the table. The index for your TABLE-ENTRIES table is IND-TABLE-ENTRIES. But you never set or reference it (this is the root of the problem). I will explain in a moment...
Notice that the WHEN part of your SEARCH is using subscript ROUTINE-CHECK. ROUTINE-CHECK was set in 500-PROCESS-FILE. Also notice that you only get to 520-WRITE-FILE if the SALESMAN-NUMBER matches the value of ROUTINE-CHECK - which it will do if a salesman with that number was read from the input file. This could work because you loaded the table such that the row number equals the salesman number back in 450-TABLE-LOAD.
Now, what happens if the input file does not contain a salesman where SM-NUMBER-IN equals 01?
Lets go through it, blow by blow...
ROUTINE-CHECK is set to 1, SEARCH is invoked and because the IND-TABLE-ENTRIES index associated with the searched table is less than the number of occurs in the table (it got initialized to zero on program load), the WHEN clauses are executed.
The first test is WHEN SALESMAN-NUMBER (ROUTINE-CHECK) = ROUTINE-CHECK. Since Salesman 1 doesn't exist, the SALESMAN-NUMBER will be zero and the test fails (0<>1).
The next WHEN clause is tried and it succeeds because (0=0); but this is a 'do nothing' option so another cycle of SEARCH is entered after IND-TABLE-ENTRIES is incremented.
Same results on this and all subsequent iterations through the SEARCHed WHEN list (none of the clauses match)... Repeat this loop until IND-TABLE-ENTRIES is incremented beyond the end of the table.
At this point the SEARCH terminates and control flows back to the next loop in 500-PROCESS-FILE. Nothing has been printed.
500-PROCESS-FILE then increments ROUTINE-CHECK by 1 (now it is 2). We have a salesman with a SALESMAN-NUMBER of 02 so we should get some output - right? Wrong! But why?
If you read up on the SEARCH verb you will find it does not reset the table index (in this case: IND-TABLE-ENTRIES). It starts using whatever value it has when the SEARCH is entered. You never reset it so it is already set beyond the end of the table. SEARCH just terminates and nothing gets printed - ever again.
Fixing the problem
Given that you have loaded TABLE-ENTRIES by salesman number in the first place, I don't see the purpose of using SEARCH. Just do something like:
500-PROCESS-FILE.
PERFORM VARYING ROUTINE-CHECK FROM 1 BY 1
UNTIL ROUTINE-CHECK > 99
IF SALESMAN-NUMBER (ROUTINE-CHECK) = ZERO
CONTINUE
ELSE
PERFORM 520-WRITE-FILE
END-IF
END-PERFORM.
Might also be a good idea to have an initialization loop for the table so that every SALESMAN-NUMBER is explicitly set to zero before you read the salesman file.
If you must use SEARCH in this program, then don't forget to set and use the associated table index variable when referencing the table being searched.
I've added this as a second answer, which I think is correct !
520-WRITE-FILE is not being performed because the SEARCH to call it is failing.
In 510-TABLE-SEARCH, I believe you need to search on the index declared for the table, IND-TABLE-ENTRIES. You will probably need to re-code 500-PROCESS-FILE and 510-TABLE-SEARCH.
In another question, you asked about the SEARCH verb. fmartin gave a link describing how it works, with examples.
Pls. Change to this:
SELECT SALESAMT-FILE-OUT
ASSIGN TO 'SALESAMT.RPT'
ORGANIZATION IS LINE SEQUENTIAL
File Status is FILESTATUS.
And add this:
01 FILESTATUS.
02 FILESTATUS-1 Pic 9.
88 SUCCESSFULL Value 0.
88 END-OF-FILE Value 1.
88 INVALID-KEY Value 2.
88 PERMANENT-ERROR Value 3, 9.
02 FILESTATUS-2 Pic 9.
88 DUPLICATE-KEY Value 2.
88 NO-RECORD-FOUND Value 3.
88 FILE-IS-FULL Value 4.
Check FILESTATUS every time u do something with SALESAMT-FILE-OUT. (u can do with the other files as well). With the help of this modification u will be able to see if there is any error when u do an IO.
This is the first step, so this is not the final answare for ure question..
"it just shows my two heading lines and then my totals-line"
In your paragraph 520-WRITE-FILE, you have the following code
IF SALESMAN-TOTAL > 0
MOVE SALESMAN-TOTAL TO DL-TOTAL
MOVE DETAIL-LINE TO SALESAMT-RECORD-OUT
WRITE SALESAMT-RECORD-OUT
AFTER ADVANCING 2 LINES
END-IF
If SALESMAN-TOTAL is zero, your program will not print detail lines. It looks like you have a data or logic error in your totalling of SALESMAN-TOTAL.
I think that you have a fairly simple problem, which has to do with your current working directory.
In the environment division, you declare the file handles and assign them to file names.
When you debug the program, the input files are in your current working directory and are therefore resolved correctly.
When you run the program, I guess you're running it from a different directory, so the input files are not resolved and therefore the output file contains only a single header line.
