Hello,
There may be some more elegant way in pl/i, but in other languages one way to do what you want is to add a 3rd module that does all of the file reads. Both AAAA and BBBB would call this new file module (FFFF) and FFFF would do all of the file access. |

So do I just need to pass the pointers amongst the modules calling FFFF(Read File Module) and keep calling it to make sure next encountered READ stmt reads the next record in the file. Right?
Or is there any special File declaration I need to make in my modules.
Thanks for your help!! |

Hello,
The only module that would have file information would be the FFFF module. The other modules would call this one and would not directly refer to the file.
If i understand correctly, yes.
When calling the FFFF module, i'd suggest passing a function (OPEN/READ/CLOSE), an End-of-File indicator to be set by the FFFF module, and a data area to receive the record read by FFFF. |

HI,
Question
-----------
AAAA is my main module reading file XXXX. I call BBBB from AAAA and i want it to read same file XXXX from next row which AAAA has already read..Please let me know if I can implement this?
Answer
---------
While reading the file from AAAA module, increase the counter for your read. Pass the counter value to BBBB wile calling.
In BBBB module, read the same file with IGNORE(counter), this will ignore the records already read in AAAAA. |
