Hello Paolo,
Just to add that you can go much higher. In both Abosft 5.0 and Absoft 10.0.2 I have had for some years now
integer MAX_LINES; parameter(MAX_LINES=
32768)
integer MAX_CHARS; parameter(MAX_CHARS=
2097152)
whereby the former is 2 to the power of 15, and the later is 2 to the power of 21.
It is some years since I changed these values and I am pretty sure I tried even higher values. It is rare that with the values above the buffer size is exceeded in a production environment, but when running test programs the resulting dialogue can still exceed the revised buffer size - but I normally give up at that point and start again.
In January 2010 I received a questionnaire from Absoft asking about improvements to the content matter of their manuals. I gave a fairly comprehensive reply, but buffer size I did not mention. Perhaps this is another area that could be explained in more detail. I remember when I initially did increase the buffer size, I was very cautious as the explanation they gave in the manual was vague
