Ok, I tested the patch (I tried to use this scratchpads for the scheme compiler) One thing I missed (or at least didn't find): How can I generate a new scope? new_pad generates a new one one the pad stack with a size which is actually smaller than the current one. Apart from that: Nice patch. bye b. -- Juergen Boemmels [EMAIL PROTECTED] Fachbereich Physik Tel: ++49-(0)631-205-2817 Universitaet Kaiserslautern Fax: ++49-(0)631-205-3906 PGP Key fingerprint = 9F 56 54 3D 45 C1 32 6F 23 F6 C7 2F 85 93 DD 47
