Dyna-Step is causing Endevor TSO functions fail with RACF errors.

Endevor ISPF interface and Quickedit are failing with RACF errors for the lack of access authority to the element catalog and other libraries used  --

IEC161I MW.NDER2.APPLDV.VR.BASE 
ICH408I USER(MWTSPM2 ) GROUP(MWD2 ) NAME(ENDEVOR SY2 PGM ID ) 841 
MW.NDER2.APPLDV.VR.BASE CL(DATASET ) VOL(GZUP01) 
INSUFFICIENT ACCESS AUTHORITY 
FROM MW.NDER2.APPLDV.*.** (G) 
ACCESS INTENT(CONTROL) ACCESS ALLOWED(READ ) 

Also getting Footprint errors attempting to do FG Adds:

C1G0119E FOOTPRINT COMPROMISED: NO IDR RECORD

The probem is in Dyna-Step 3.1 which should swap to the Alternate UserID.

There is a parameter that must be added to the startup configuration for Dyna-Step's DYSSERV server:

DYNASPCL DISP=SHR,
COMPAT=ENDEVOR,                       <<== Add
FILE=STEPLIB,
FREEALL=NOFREEALL

This is an assembler macro, the options can be dynamically assembled at startup if the server is configured for that.

This fix is not documented in the Dyna-Step manual and there is no mention of it in the samples in the product target libraries.  This was not found on the Dyna-Step support site either.
