Using Z Data Tools functions in REXX procedures or TSO clists

To call a Z Data Tools function from a REXX procedure, use the following syntax: 
HFMMAIN "$function-name-parameters"
To call a Z Data Tools function from a CLIST, use the following syntax: 
HFMMAIN $function-name-parameters
Join the parameter names and values with an equal sign or a blank. Separate these pairs with a comma or blank. For example: 
HFMMAIN "$DSP DSNIN='HFMUSER.TEST.KSDS1',FORMAT=HEX,KEY=000100,NLRECS=20"

Within a REXX procedure, all profile settings are taken from the installation defaults. For details on changing Z Data Tools default profile settings, see Z Data Tools Customization Guide .
