This chapter contains information about the Z Data Tools functions that you can use to perform Z Data Tools tasks. It also contains information about the Z Data Tools-supplied REXX external functions that can be used in REXX procedures and template criteria expressions run within Z Data Tools.

The Z Data Tools functions can be invoked from batch jobs using JCL, within TSO as commands, and from REXX and CLIST procedures. The REXX external functions are only made available to a REXX environment running under the control of a Z Data Tools function.
