25. Keywords and Names

Most keywords are reserved words and can not be used as column names (in the format command) or as variable names (in the symbol table). The only exceptions are the two-letter keywords RC, CR, on, and OR, for convenience since two letters can be used in A0 format to name columns in the default spreadsheet size.

OR is case-insensitive when used as an operator or column name, but is case-sensitive when used as a variable name.

Column names can be used as variable names.

The named operators (NOT, AND, XOR, OR, IMP, EQU, int, long, double), the names of the numeric and range functions, and the names of the commands are all keywords.

stdout, byrows, bycols and the print options constants, formats, formulas, functions, pointers, states, symbols, values are all keywords.
