Warning XS0165 Use of possibly unassigned local variable xxx

This is probably not preventable but basically the warning is incorrect:
Warning XS0165 Use of possibly unassigned local variable cXXX
Code:
Code: Select all
local cXXX as string
if (some condition)
cXXX:="A"
else
cXXX:="B"
endif
I understand that I can prevent the warning by assigning some dummy value in the initialization but the warning is incorrect in the above code (The if..else..endif always runs, is not conditional)

Dick,
There must be something else. When I try this with X# 2.20 then this compiles without warnings.
Code: Select all
FUNCTION Start as void
local cVar as string
IF Time() < "12:00"
cVar := Time() + " AM"
ELSE
cVar := Time() + " PM"
ENDIF
? cVar
WAIT
RETURN

Hello Robert,
Hmm, as I assigned something to all the variables in the meantime and simplified the code for posting I can't find it back to check if something in the code made the warning valid after all.
If I encounter the warning again I will double check if something could cause it. As you tested the code below I assume for now I must have missed something that makes the warning valid.
