Symbols

Symbols must consist of one-to-eight characters and begin with an alphabetic character (A-Z) or one of these special characters: @, #, or $.

Numerals (0-9) can be used in the second and subsequent character positions.

Warning

Note

You should try to avoid creating symbols that might be confused with hexadecimal values (for example, symbols that contain only the characters A through F and 0 through 9.

Symbols are replaced by their definition as they are encountered, and then the result is processed. Therefore, the definition of a symbol can (and frequently does) contain another symbol. For example, the definition of the predefined symbol ASXB is ASCB+6C?, the definition of ASCB is PSAAOLD?, and the definition of PSAAOLD is 224. Therefore, the symbol ASXB will be converted to 224?+6C? by the expression processor. The address at PSAAOLD is the address of the target address space's ASCB.
