These are all interesting ideas but still require the user to know ahead of time that the problem of mismatched extensions exists and how to work around it. The LOAD"0:PROG.DO” might be the easiest thing to recommend once someone realizes they have this problem, but then that also requires they know a bit more about TS-DOS.
Thanks for the ideas, Jeff Birt First of all there's Load"COM:98N1E Or Run"COM:98N1E Even better if you are using TSDOS I believe you just need to use it in DOS-ON mode. LOAD"0:PROG.DO should load a text encoded BASIC program in one step IIRC. -- John.
