It is possible to send instructions to the expression evaluator directly, i.e. to avoid some steps in the interpretation of commands. This can be done by giving the instruction
- interpcom -> [
(or by putting a line containing a single [ in a program file or a program). All subsequent instructions will be sent directly to the expression evaluator. In programs, this will not affect the use of loops, goto and if... statements. To be able tu use commands again, the following instruction
- interpcom -> ]
must be used (or a line containing a single ] in a program file or a program).
The instructions
- interpcom -> [0
and
- interpcom -> [1
are variants of [. They are used to increase the speed of parts of programs that use only the expression evaluator. As for [, between one of these instructions and ], all statements are sent directly to the expression evaluator, and additional optimizations are made (see 7 for more details).
