You got me... almost exactly one year ago I updated all my EXECs to become 'RTNSTATE DMSINXED' if Rc<>0 then do; 'SUBCOM XEDIT' ; Xedit=(rc=0); end else do; call csl 'DMSINXED RETC REAS T'; Xedit=(reas=0 & t=0) ; end But, this SIGNAL SAMPEXEC didn't have filetype EXEC (nor XEDIT, nor REXX), hence I missed it.
