Using built-in functions z/OS TSO/E CLISTs SA32-0978-00 |
|||||||||||||||||||||||||||||||||||||||||||||||||
The CLIST language includes built-in functions that you can perform on variables, expressions, and character strings. If necessary, CLIST evaluates the variable or expression first, and then performs the requested function. The CLIST then stores the result under the name of the built-in function. To use a built-in function, type its name, followed by the variable, expression, or character string in parentheses. The variable, expression, or character string is also called the argument of the built-in function. The argument must immediately follow the built-in function name, with no blanks between them. Table 1 describes each of the built-in functions briefly and gives page numbers where you can find more information.
In addition to these built-in functions, TSO/E provides an installation exit that lets your installation add its own CLIST built-in functions. For information about the exit, see z/OS TSO/E Customization. Note: With the exception of &SYSNSUB, built-in functions will
not resolve double ampersands (&&) that appear in an argument.
