The IBM BASIC.COM will only run on systems that have the Cassette
BASIC ROMs installed. The program calls the ROMs for many, *many*
functions.
The BASICA.EXE you refer to could be *anything*. It's likely some form
of GW-BASIC. But depending on where you got it, it may be intended for
a *specific* vendor's hardware (I have a BASCICA here that supports the
odd video modes of this non-standard system).
When you just type "BASICA", what does the copyright message say? It
will give a version number, *and* likely list the company it was
licensed to.

This sounds like "protected" code. If it is, there are several programs
which will remove the protection.
