Note |
Symbolic names are recognized indifferently if they appear in lower or upper case. A name is recognized only if it forms a word by itself, while it is ignored if it is part of a longer word. Symbolic names are not allowed to be defined equal to any reserved word of the R3 language |
The purpose of this command is to return either a more compact or more intelligible program source.
The definition must precede use; otherwise a compiler error message will result.
Instruction literally does not cause a lengthening of the object code produced by the compiler; it may, however, cause a lengthening of compile time.
