History
What´s new in version 5:
* Incorporated Ingo Berg´s MuParser routines into Hi65. They form an open source evaluator of mathematical expressions, that enables Hi65 to evaluate and calculate expressions (e.g. for variable assigns) with an even higher complexity than what a physical Commodore 65 could do. However, they are disabled by default in Hi65 for speed reasons (the native Hi65 expression evaluator is limited to expressions with at most one operator, but is over 275 times faster to evaluate them). The MuParser routines can be toggled on or off with the Hi65cfg utility, from the Hi65 Edit and Launch Tool, or directly from Hi65 with a pseudocommand (see below).
* Implemented a BASIC 10 pseudocommand to enable, disable or verify the status of MuParser within Hi65. The syntax is: MUPARSER 0 to disable it, MUPARSER 1 to enable it, and just MUPARSER to display a message telling you whether it´s currently on or off. It works either from the command line or from within a BASIC 10 program.
* Added 36 new error messages that do not appear in the physical Commodore 65, that are triggered whenever MuParser fails to evaluate an expression for some reason. This does not affect compatibility and makes debugging programs easier because they are more specific than a generic "SYNTAX ERROR" could ever be.
