X'001C' ENTRY - INVALID CMD/GCMD/ISRT CALL

Explanation
  IQCQMRQ0 was called with an invalid CMD, GCMD,
or ISRT call, or an invalid sequence of these calls. The first MRQ/QCF
call to IMS must be a CMD or
ISRT call.  CMD calls must pass a valid command work area.  ISRT calls
must pass a valid MRQ prefix and IMS message.

Programmer response
 If the caller is the MRQ or QCF client,
then this is either an MRQ, QCF, or IMS error.
This problem can also occur if the  release of MRQ or QCF is not supported
on the IMS release. Verify that
this is a valid MRQ/QCF release for this release of IMS.
