Problems with awk / nawk

[Makasy, Christine (USB)]

Hi,
I'm not sure whether I use the right forum for my question / problem. But
nevertheless you maybe can help me.

The use of nawk produces the following error message: String /..../... too
long at source line 1. 
Which settings do I need to change? 
(Just for information: On different installations the process / program
runs.)

Many thanks in advance for your support.

Regards
Christine
