Symbolic parameters offer a convenient way of changing a procedure to fit your requirement. Consider the example procedure-proglod, sysctl, sym,etc. are all symbolic parameters.

Symbolic parameter names may consist of from one to seven alphanumeric or national characters preceded by an ampersand. The first character however must be alphabetic / national. Exec statement keyword parameters may not be used as names of symbolic parameters.For e.g.. & REGION. This restriction does not extend to DD statement keyword parameters.For e.g. &DSN can be used as symbolic parameter.
