WinHugs question

Hi, I'm rewriting WinHugs. I have rewritten the vast majority of it now, it has nicer styles, prettier bits, less code, more standard controls and hopefully adding unicode support should be easy once its all working. I think I'm about 2 weeks away from using the new version for myself, and a month from a beta version. The only thing I'm "stuck" on is actually executing a command. I basically want to fire "123" at the hugs program and have it evaluate. It seems that WinHugs currently has lots of global buffers, and in some way I haven't spotted those buffers get transferred into the hugs system and evaluated. Is there any function roughly like "evaluateCommand(char* Command)" anywhere in Hugs? Thanks Neil
