The default character set used by the IBM PC is different than the HP Roman-8 character set used by HP BASIC. The differences exist in characters CHR$(128) and above. In HTBasic, all characters from CHR$(128) through CHR$(254) are allowed in variable names. If you will be running a program with HP BASIC and HTBasic, you should restrict variable names to characters from CHR$(161) to CHR$(254) and the legal characters less than CHR$(128). Chapter 12 of the User’s Guide, "International Language Support," contains information on converting from the HP character set, or setting up the PC to use the HP character set.
