[Info-Ingres] Ingres ABF 4GL macros

[Paul M. via DBMonster.com]

hi all,

I a previous job I had at an Ingres site, in the 4GL code we use to put one
line macro labels that were expanded out to several lines of common code,
that would be visible in the final object code.

Being a raw graduate at the time, I didn't take much notice, but I am now
wondering how that was actually accomplished?

I don't beleive now that this is an Ingres ABF feature, but rather something
that was done at the OS level, in this case unix, like a big sed script.

Can anyone shed some light on this?


regards,

Paul M.
