VM/SYSTEM PRODUCT RELEASE 3
5664-167
SYSTEM PRODUCT INTERPRETER
__________________________
The System Product Interpreter is a new command and macro
processor. It can be used for interpreted applications,
command processing and generation, for macros such as those
used by the System Product Editor, as a desk calculator,
mathematical problem solver, or for any other purpose for
which an interpreted simple-to-use language is suitable.
Syntax is in a high level form which is easy to learn.
Highlights of the System Product Interpreter include:
- Extended Control Structure:
If-Then-Else
Select-When-Otherwise-End
Do-Iterative-End
Iterate and Leave
- Full set of arithmetic, character, and logical operators
- Selection of Standard functions
- Free Format, Mixed Case
- Interactive Debug
- In line Function and Subroutine calls
- Decimal and Scientific arithmetic capability.
- Built-in string parsing instructions
The System Product Interpreter will be the primary interpre-
tive command and macro processor for VM/SP in the future.
It is intended that all future enhancements will be applied
to the System Product Interpreter. EXEC and EXEC 2 will
remain supported and will coexist with the more powerful
System Product Interpreter.
