Usage of cobol program in QTP

[Richard Schilling]

Wow - this sure brings back some memories.  I've had a lot of experience 
interlacing COBOL jobs among QTP jobs (QUIZ, QUICK as well, actually). I 
took a Powerhouse process that took more than twelve hours to run and 
cut it down to less than four (if memory serves) by interlacing QTP and 
COBOL processing.  Works great!

I think Guy mentioned he uses it when the logic is just easier handled 
in COBOL - which is generally what I found the case to be.  I also found 
this to be necessary when the amount of time it takes for QTP to process 
data is too long - say, nightly system maintenance kills your process 
every night at midnight.  It's better to export the data to flat files, 
and allow one or more COBOL programs to chew on the data.

Basically, what you do (as others have suggested), is setup QTP or even 
QUIZ to generate some data for the COBOL application to work on, and 
then you call the COBOL program to molest the data you just generated. 
Then, QTP picks up the data again.  Use temporary files as much as possible.

Works really well when you take the time to set up the batch files and 
scripts to coordinate the calls to QTP and COBOL.
