Write Error

Write Error

(OP)

Hi my name is Cinthia , i am in my beginning semester of COBOL and in chpt 2 of the Shelly Cashman book Structures COBOL Programming. I am trying to run a report and i go the mistake message "wrong open way or access way for write [error 148].

I have compiled and there are no syntax errors , but when i press run i get that fault. Any suggestions? This is very very new to me

RE: Write Error

Cinthia,

i don't know which compiler you use, or on which platform, merely finding out what that "Error 148" means is a practiced commencement.
Some possible causes: did you Open the file you are writing to before the get-go WRITE ? And if so, did y'all Open up for OUTPUT ?

RE: Write Error

(OP)

I am using Win 98. Dont you open by going to open for execution? Then i click RUN. Maybe i'1000 doing it all wrong and my instructer wont help at all.

RE: Write Mistake

Cinthia,

When y'all say 'Dont you open past going to open for execution?' it looks like you are refering to the actually running of the program and not where your problem is (ie. in your code).
You lot need to look at (i) the 'Select' argument(s) in your Environment Segmentation and make sure you have the correct file access mode (sequential, dynamic, whatever). Then (two)make sure the 'open' statement(s) for the file(south) are correct (eg. you don't desire to open for input when you are going to write to the file). Finally check (3) the file access statements (write, read, any) in your procedure sectionalization. It looks like yous have a mismatch betwixt (i), (2) and (three).
Good Luck

RE: Write Error

Cinthia,

just to add to what kfmason said:

is your program supposed to read from or write to a file?
If it's reading, and suppose your file is chosen INPUT-FILE (in the source), yous should find:

- in the INPUT-OUTPUT SECTION, something like

   SELECT INPUT-FILE ASSIGN TO ... (i don't no what that is, but i'thou sure you lot exercise)

- in the FILE Section, somthing like

   FD INPUT-FILE
        ...
    01 INPUT-Record ...
...

- somewhere in the PROCEDURE Partition:

...
Open INPUT INPUT-FILE.  (This is the Open argument i mentioned earlier)
...
READ INPUT-FILE.
...
Shut INPUT-FILE.

For output files, that is files you write to, it's basically the aforementioned, except the procedure division bit:

...
Open up OUTPUT OUTPUT-FILE.
...
WRITE OUTPUT-Record.
...
Shut OUTPUT-FILE.
...

So, in short: you take to employ the Open argument to really open the file for use within the program. If y'all don't, or not correctly, you'll become the mistake you mentioned.

Proficient luck !
