Subsystem Exit Invocation, Rules, and Guidelines

The user exit, which must be named MFJYssss, and where ssss is the subsystem-name, is optional and is invoked as follows:

CALL 'MFJYssss' USING SXIT

Where SXIT is the user exit interface block (mfjdsxit.cpy). It contains

mfjdsxit.cpy describes in detail all of the event codes, actions codes, and the data associated with each event. When looking at mfjdsxit.cpy, note the following:

The subsystem exit is called as events occur.

If the user exit fails for any reason, it is disabled in the failing process for all subsequent events.

Note:
  • The user exit must be named mfjyssss.cbl. The source for each sample exit is available in %ProgramFiles(x86)%\Micro Focus\Enterprise Developer\src\enterpriseserver\exits (Windows) or $COBDIR/src/enterpriseserver/exit (UNIX). We recommend you use this as the base to build an exit to suit your needs. It uses a copybook for SXIT (the subsystem exit interface block). The source for this copybook, mfjdsxit.cpy, is in %ProgramFiles(x86)%\Micro Focus\Enterprise Developer\cpylib (Windows) or $COBDIR/include (UNIX). A listing of mfjdsxit.cpy is provided in the topic Subsystem Exit Interface Block (mfjdsxit.cpy).
  • The subsystem exit must use the ASCII (ANSI) character set. We recommend that it uses the non-mainframe COBOL dialect as it is a PC-specific program.
  • The exit is optional. The .dll (Windows) or .so (UNIX) file for the subsystem exit must be placed in a directory that is specified in the search path of PATH (Windows) or $COBDIR (UNIX). If you want it to be in a location independent of the project, then you may place it in %ProgramFiles(x86)%\Micro Focus\Enterprise Developer\bin (UNIX).
  • You must write the subsystem exit in COBOL.
