To all who replied, thank you.
Yes, I tried the FOPEN, FWRITE, FCLOSE scenario.
In my Cobol mainline I FOPENed the file, gave me the file number which I
passed to the Pascal sub to do the FWRITE. The FWRITE failed with CC >
zeroes (CCG).
I tried to write an 80 byte char field to this file and the FWRITE failed.
Couldn't figure out why as the opened file is larger than 80 bytes.
FOPENed PASC001 OK
FCLOSE PASC001 OK
FOPENed PASC001 OK=>+0032<
1) THE REC-LENGTH =>-7060<
1) FILE NUMBER GOING IN=>+0032<
Processing:EXEC <
FWRITE BOO BOO, CC > ZEROES
I did a LISTFTEMP,2 after the program ran to see how many records were
written to the file and as you can see none were written at all:
listftemp,2
TEMPORARY FILES FOR MGR.E3K,PUB
ACCOUNT= E3K GROUP= PUB
FILENAME CODE ------------LOGICAL RECORD----------- ----SPACE----
SIZE TYP EOF LIMIT R/B SECTORS #X MX
PASC001 7060B FA 0 0 1 0 0 * (TEMP)
