Array processing with SET symbols

Edit online

You can use the SET statement to assign lists or arrays of values to subscripted SET symbols. For example, a list of 100 SETx values can be coded in one extended SETx statement. The extended SETx statement has the following format:

Name      Operation      Operand

&SYM(exp) SETx           X1,X2,,X4,…,Xn

where:

&SYM: is a dimensioned SET symbol
exp: is a SETA arithmetic expression
SETx: is SETA, SETB, or SETC

An operand can be omitted by specifying two commas without intervening blanks. Whenever an operand is omitted, the corresponding element of the dimensioned variable SET symbol (&SYM) remains unchanged.
