Hi Fernando,

You got error message because you've double "=" sign in the expression.

cRem = = RTRIM(cSourceString, SPACE(1), CHR(10), CHR(13))

>There was yet another test to be made: with the VFP 9 rTrim() function as you suggested, and here it is. BTW, looking at VFP9's help file I couldn't find that syntax you've presented. How did you get to it? The second test rTrim() syntax gave me an error message when trying to use it.

>>In VFP9 you could use RTRIM() function

>>cString = RTRIM(cString,0, SPACE(1), CHR(10), CHR(13))
>>* or
>>cString = RTRIM(cString, SPACE(1), CHR(10), CHR(13))

>>>What is the best/fastest way to remove trailing carriage returns/line feeds from a string?

>>>Example:
>>>

>>>cString = "This is what I want to keep!"                         + ;
>>>          Space (10) + Chr (13) + Chr (10) + Chr (13) + Chr (10) + ;
>>>          Space ( 1) + Chr (13) + Chr (10) + ;
>>>          Space ( 1)

>>>After execution of the routine, all trailing blanks/CR/LFs should be removed (last 18 characters removed, first 28 characters ketp).
