The following is code taken from my SWOS Editor released in 1996, this shows the "ELSE" command working.
Code:
.load:
RTEZSetPattern 0,"#?.CAR"
fi$=""
f$=RTEZLoadFile("Select Your Save Game file",fi$)
If f$
flength.l=Exists(f$)
InitBank 1,flength,1
aa.l=RTLockWindow (0)
LoadBank 1,f$
lo.l=BankLoc(1)
RTUnlockWindow 0,aa.l
ld=1
JSR _enable
Else
body$="You MUST select a SWOS Game":ok$="_Retry|_Cancel":JSR _req
Select ab
Case 0 : If ld=0 : End:EndIf
If ld=1 : Goto loop:EndIf
Case 1 : JSR load
End Select
EndIf
JSR checkver
JSR _peek
