RE: RCVF - how to do multiple CHAINS in one CL pgm

Thanks for the good idea, I tried it but it doesn't work.

Any other ideas? Is calling another pgm the only way?


The OVRDBF only works once - just for the file open. The follow-on DLTOVRs are ignored by RCVF.

The IBM manual states the following; although it is not totally accurate. It does work one time, but not more than once.

Setting a position in the file
Note:
File positioning by means of the Override with Database File (OVRDBF) command does not occur until the next time the file is opened. Because a file can be opened only once within a CL program, this command cannot be used within a single CL program to affect what will be read through the RCVF command.

Maybe

Top:
Load keyValue
OVRDBF FILE(TestFile) POSITION(*KEYAE 1 *N &KeyValue)
Rcvf
DLTOVR FILE(TextFile)
goto Top

I have a CL loop as follows:


Top:
Load keyValue
OVRDBF FILE(TestFile) POSITION(*KEYAE 1 *N &KeyValue)
rcvf
goto Top





The OVRDBF positions the file ONLY the first time thru (apparently it only positions for the NEXT file open).


How can I read the record that I need (using keys) several times in on CL run?


Thanks!
