...Its obviously working...
You sure? CALL will not generate an abend if the file (or path) does not exist.
Older versions of KiXtart (e.g. 4.53) will set @ERROR, but it is up to you to decide if it is significant or not.
So the script may be running to completion without error but if your missing files were supposed to be doing something useful then they are not doing it any more.
The missing files could of course be optional or obsolete code, in which case the fact that they are missing is not significant.
