Hi! I'm trying to run some pascal with java. After Markus Gerwinsky help and some hard work getting libgpc to be shared library it is possible. The problem that the first example I tried was printing something from Pascal with writeln. Then I got a runtime error that Output variable is uninitialized. Shouldn't gpc work with standard descriptors or the StdOut, StdErr and the rest should be initialized somehow? also how should I initialize them? To what device/descriptor etc? opening file and writing into it works. Nick
