Altair 680 CSAVE Problems!@ : (

I'm having a ton of trouble saving a program on a cassette tape using Altair 680 basic. Was there a KCACR basic made without the CSAVE command? My basic appears to have a CSAVE command, but it won't accept the name!!!!! : ( I'm sending this to two groups. I've been at this problem for hours now... : ( I'll post a transcript below. Let me know what I'm doing wrong! : ( -------------------- .J FD00 (cassette bootstrap rom address) (basic loading) (basic loaded) .J 0000 (run basic...) MEMORY SIZE? TERMINAL WIDTH? 80 WANT SIN-COS-TAN-ATN? YES 9604 BYTES FREE MITS ALTAIR 680 BASIC VERSION 1.1 REV 3.2 --KCACR-- COPYRIGHT 1976 BY MITS INC. OK 10 PRINT "HELLO" 20 GOTO 10 CSAVE A ?TM ERROR OK -------------------- TM is a type mismatch error. SM is for a command it doesn't understand. Watch... -------------------- CSAVE A ?TM ERROR OK CSAVE ?SN ERROR OK AHHHH! ?SN ERROR OK AHHHH! A ?SN ERROR OK -------------------- Am I wrong assuming that because it gives me a TM error instead of SN that it is "trying" to work? I get the same things for CLOAD... How in the world are you supposed to save something to tape! : ( If I have the wrong version of basic, anyone have the right one? What will it take for me to get a copy! : ) (first smile in this e-mail... ; ) ) Thanks, Grant
