Implementation Restrictions
The name of a variable or label, and the length of a literal
string may not exceed 250 bytes. More characters than 250
will be truncated.
- The internal represantation of a clause (after removal of
- comments, extra blanks etc.) may not exceed 500 bytes.
| Numbers follows C restrictions, thus integers are long and
| real numbers are held as double.
| The FOR and simple counts on a DO instruction, and the
| right-hand term of an exponentiation may not exceed maximum
| long number.
The control stack (for DO, IF, CALL, etc.) is limited to
internal stack of the computer. For MsDos rexx the maximum
recursive level will be round 70-80.
Functions and subroutines cannot be called with more than
10 arguments.
| Input & Output cannot be redirected for commands executed
