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

Vendor response

My Control Language for Files (CLF) product handles this type of situation
quite nicely. The command Read Record using
CLF<http://www.powercl.com/clf/clfcommands/readrcdclf> allows
you to read by key using a list of key values with the KEYLIST keyword, a
structure containing the key values with the KEYSTRUCT keyword, the key
relationship desired with the KEYREL keyword, etc.

The READRCDCLF command is provided as part of the no-charge run-time of CLF
(base option) and can be used in conjunction with the Open File using CLF
command (also part of the base run-time). Using only the no-charge option
you would need to provide a structure describing the fields/columns of the
record being read (think program-described here).

Using the CLF precompiler (part of the fee-based option 1 of CLF), your CL
program could simply Declare the file using DCLFCLF (think
externally-described here), Open the file, and then start reading records
(sequentially, randomly, etc).

More information on the product can be found
here<http://www.powercl.com/clf/aboutclf> (and
various articles I've written over the years).

End of vendor response.

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!
