You can use symbols in the following ICETOOL operators: COUNT, DATASORT, DISPLAY, OCCUR, RANGE, SELECT, SPLICE, STATS, SUBSET, UNIQUE, and VERIFY. In general, you can use symbols in these ICETOOL operators where you can use constants ('string', n, +n or -n) and fields (p,m,f or p,m). See the discussion of each operator in Using ICETOOL for a description of its syntax.

ICETOOL reads the SYMNAMES data set once and uses it for all operators and DFSORT control statements for the run. You can use symbols in operators from the TOOLIN data set or your parameter list. You can also use symbols in DFSORT control statements in xxxxCNTL data sets or in the DFSPARM data set (see Using symbols in DFSORT statements for details).

ICETOOL will list the original operator statements as well as the transformed operator statements.

Details of the use of symbols for each applicable ICETOOL operator is given later in this section followed by a complete ICETOOL example. The example is meant to illustrate variations in how symbols can be used and how they will be transformed. Therefore, the example does not necessarily correspond to how symbols would be used in real applications.
