system()

When I try to make a call to the system() procedure, I get this compiler error: testex.p: In function `program_Testex': testex.p:4: undeclared identifier `System' (first use this function) testex.p:4: (Each undeclared identifier is reported only once testex.p:4: for each function it appears in.) Is there something else I must include in my program? I am using gpc-2.0 compiled for the linux 2.0 platform. ----Geoffrey Arnold--- garnold@cyberdrive.net
