Problem:

We have a CALL to an IBM module, IGZERRE. I can not find any Mainframe Express equivalent for this. What can I do?  

Resolution:

  IGZERRE is an IBM Language Environment preinitialization module. In MFE one does not need it but if your Cobol or Assembler has a hard external reference for it (generated by the CALL statement), then you can use this emulation program:

IGZERRE  CSECT

R14      EQU   14

R15      EQU   15

         SR    R15,R15            RETURN CODE = 0

         BR    R14                RETURN

         END
