SET symbol definition

If you declare a SET symbol to have local scope, you can use it only in the statements that are part of:

• The macro definition in which it was defined, or
• Open code, if it was defined in open code

If you declare a SET symbol to have global scope, you can use it in the statements that are part of:

• The same macro definition
• A different macro definition
• Open code

To help you with SET symbol definition, High Level Assembler provides the following facilities:

• A SET symbol is declared implicitly when it appears in the name field of a SETx instruction, and it has not been declared in a LCLx or GBLx instruction. It is assigned as having local scope. If the assembler subsequently encounters any local scope explicit declaration of the symbol, the symbol is flagged as a duplicate declaration. A SET symbol is declared as an array if the name field of the SETx instruction contains a subscript. See Array processing with SET symbols.
• Global and local SET symbol declarations are processed at conditional assembly time. Both a macro definition and open code can contain more than one declaration for a given SET symbol, as long as only one is encountered during a given macro generation or conditional assembly of open code.
• A SET symbol can be defined as an array of values by specifying a subscript when you declare it, either explicitly or implicitly. All such SET symbol arrays are open-ended; the subscript value specified in the declaration does not limit the size of the array, as shown in the following example:

    Name      Operation      Operand

              LCLA           &J(50)
    &J(45)    SETA           415
    &J(89)    SETA           38
