Angel,
Can you tell, if Xbase++ support negative indexes
in 'string[ n ]' operations?
I'd also be interested in the error messages you get
when using off limit or zero index.
Brgds,
Viktor
Sure !!!
See next:
PROCEDURE Main
LOCAL cString := 'ABCDEFGHIJ'
? ' 2 '+cString[ 2] // ----> B
? '-2 '+cString[-2] // ----> I
? ' 0 '+cString[ 0] // ----> ERRORLOG A
? '15 '+cString[15] // ----> ERRORLOG B
RETURN
/*
ERRORLOG A
