Hi Iain, I'm working with UNIX only but likely my change will solve your problem too. Iain> I was running some scripts in WinHugs, and everything was Iain> running happily. I then attempted to add ( using ":a" ) a new Iain> script, and received the following error message: "Program Iain> code storage space exhausted". In the "src" directory, there are some parameters defined in "prelude.h". Our settings are (we use LARGE_HUGS): #define NUM_ADDRS Pick(28000, 60000, 1280000) #define NUM_STACK Pick(1800, 12000, 64000) NUM_ADDRS is for the program code storage space and NUM_STACK for the stacksize. Recompile, maybe it'll work.
