Names

Format

Programmer is free to give names to labels, variables, arrays and functions as long as the names match the following regular expression:

/^[A-Z][A-Z0-9.]*[%!$]?/

The format of the definition and the reference are the same. See [References] page for details.

Parenthesis is Mandatory for Functions and Arrays

Both function and array names must be immediately followed by a left parenthesis. That is, no whitespace in between is allowed.

• There is no possibility to refer to a whole array instead of a single element in it.
• Nullary arrays as well as such functions must be followed by an empty pair of parentheses.
• There is no possibility to refer to a function rather than calling it.

Keywords

Instruction names formally match the pattern, but you will get various errors if you use them as names. See [Hacks]
