Subject: IF NOT %FOUND
So this bug came up in a pretty old program that I'm surprised that it hasn't been an issue before today. My question is, when DOU %EOF and If NOT %FOUND is used, without specifying a file, is always just using the last read file?
Below is most the relevant code. The previous programmer didn't specify the filename on the commands. Adding 'FILE1' to them fixed the issue, so it is technically solved, but I just want to better understand myself why it wasn't working.
In this case FILE1 had two matching records for the key. The first record processed okay, it goes down to the end of the DO loop and the next record is read. *(I ran it in debug so I know the program found it. It immedially went back up to the top of the do loop, and then on 'IF NOT %FOUND' it came up as not found, which surprised me as FILE1 was the last file to be read and it did find the next record. Am I misunderstanding something? Again, the program worked fine adding the proper file to the command.
C KEY1 SETLL FILE1
C KEY1 READE FILE1
C DOU %EOF
C IF NOT %FOUND
...
C ELSE
...
C KEY2 CHAIN FILE2
...
C KEY3 SETLL KEY3
C KEY3 READE KEY3
...
C ELSE
C KEY1 READE FILE1
C ENDDO
