Did you try to start the program by RUN or START?
RUN 100 would save i guess the compiled porgram.
I write a "Hello World" program called HELLO.BAS
I compile it and I take HELLOZ.BAS HELLOZ.Z
Then LOAD "HELLOZ.BAS" and RUN 100 and PRESS ENTER when INPUT PROMPT appears
Nothing pass
Alternative
LOAD "HELLOZ.BAS"
I change B$ y A$ in line 120
when INPUT PROMPT appears I type HELLO.COM
File HELLO.COM is created in disk
I try launch it
:LOAD HELLO.COM
the program don't work
I n00b in Elan Enterprise, so sorry.
