This version of BASIC runs on RSX, IAS, and VMS. For VMS, Delete BASPRE.MAC. Rename BASPREVMS.MAC to BASPRE.MAC Edit BASPRE.MAC or use the BASPRE.MAC on [300,23] of this tape, then use the following commands (also on 11M) MCR MAC @11MASMVMS MCR TKB @BIGBASIC To use on VMS, define as a foreign command. For example, copy RSXBASIC.EXE into SYS$SYSTEM: and define BAS:==MCR RSXBASIC and you'll have it. Note that these commands will work for RSX11M or M+ also, and create a version that runs OK on P/OS as well. NOTE: Commands to BASIC must be in UPPER CASE, otherwise you get error messages. Thanks to Frank Borger who made this all possible.
