The normal equate expressions are tokenised and converted into this language for processing. An understanding of this language can be useful for debugging purposes as this is what any trace output will currently show.
All operators are single or double character combinations.
Five interchangeable data types are supported. The language is stack based but in addition global variables, local variables, and system variables are available. Most operators accept an immediately following variable operand instead of one stack operand. Looping and conditional structures can also be used - as well as a function call mechanism. All in all there are a total of about 34 unique operators, some of which have multiple functions dependent on the data types of their operands.
