SET Symbols SET Symbol Specifications SET symbols can be used in model statements, from which assembler language statements are generated, and in conditional assembly instructions. The three types of SET symbols are: SETA, SETB, and SETC. A SET symbol must be a valid variable symbol. The rules for creating a SET symbol are: The first character must be an ampersand (&) The second character must be an alphabetic character The remaining characters must be 0 to 61 alphanumeric The first four characters should not be &SYS, which are used for system variable symbols Examples: &ARITHMETICVALUE439 &BOOLEAN &C &EASY_TO_READ Local SET symbols need not be declared by explicit declarations. The assembler considers any undeclared variable symbol found in the name field of a SETx instruction as a local SET symbol, and implicitly declares it to have the type specified by the SETx instruction. The instruction that declares a SET symbol determines its scope and type. The features of SET symbols and other types of variable symbols are compared in Figure 86. Figure 86 (Page 1 of 3).
