Subscripted SETC symbols

The SETC symbol (see  1  in Figure 1) in the name field can be subscripted. If the same SETC symbol has not been previously declared in a GBLC or LCLC instruction with an allowable dimension (see  2  in Figure 1), or has been implicitly declared in a SETC instruction as a scalar (unscripted) variable symbol, then the symbol is implicitly declared as a local SETC array variable.

The assembler assigns the character value represented in the operand field to the position in the declared array (see  3  in Figure 1) given by the value of the subscript. The subscript expression must not be 0 or have a negative value.
