Subscripted symbolic parameters must be coded in the format:

&PARAM(subscript)

where &PARAM is a variable symbol and subscript is an arithmetic expression. The subscript can be any arithmetic expression allowed in the operand field of a SETA instruction (arithmetic expressions are discussed in SETA instruction). The arithmetic expression can contain subscripted variable symbols. Subscripts can be nested to any level if the total length of an individual operand does not exceed 1024 characters.
