PARMs are not being passed from JCL to COBOL program. When the program is executed, a "203 CALL parameter not supplied" error message is issued.

The COBOL program did not contain any CICS commands but 'EXEC CICS' was selected in the project settings. Under the 'File' tab of the MFE project window, highlight the project folder and then go to Project > build settings for project. Click on the 'preproc' tab, and uncheck the box marked 'EXEC CICS', then click OK.
