TEST= parameter for procedures
Use the TEST= parameter in procedures to specify whether (1) or not (0) the addresses in your call list should be checked for validity. Valid values are 0 or 1.The default is 0.
VALCK= is used instead of TEST= in the DFSOPT DD statement in IMS-supplied procedures for BMP and JBP regions. See VALCK= parameter for procedures.
For more information, see DFSOPT DD in DD statements for IMS procedures.
A value of 0 or 1 must appear in the generated JCL statement for this parameter. An address is invalid if it is either lower than the lowest address not in the z/OS® nucleus or higher than the highest address in virtual storage of the machine.
