Hi, Now that gpc runs, I compiled and tested the bigsetdemo sample program that comes with gpc. I am concerned with that since the SUN Pascal code I must convert to GNU Pascal uses some big sets. The program works, but outputs all the values I enter minus 1. I don't see anything strange in the source so, is there a bug in the 'set' mechanism? Here is a sreenshot of the bigsetdemo program: <Sigourney> bigsetsdemo Enter some numbers between 1 and 100000 (one or several per line). Enter an empty line when finished. 2 56 21 You entered the following numbers: 1 20 55 <Sigourney> bigsetsdemo Enter some numbers between 1 and 100000 (one or several per line). Enter an empty line when finished. 1 8352 76 You entered the following numbers: 75 8351 <Sigourney> Pascal Viandier pascal@accovia.com
