Hello Hugo,

The example is useful and almost correct. Here how I tested it:

cText1 = 'Text1' + space(5)
cText2 = 'Text2'
? cText1 + cText2   && returns 'Text1     Text2'
? LEN(cText1 + cText2)   && returns 15
? cText1 - cText2   && returns 'Text1Text2     '
? LEN(cText1 - cText2)   && returns 15

While it is almost useless for output intended for reports, it would seem to be useful for index expressions. For example, instead of

INDEX ON  PADR(TRIM(lastname)+TRIM(firstname),25)  TO blahblah

it would be simpler (and much more readable) to

INDEX ON  lastname-firstname  TO blahblah

I have read messages here and elsewhere that index expressions do not _have_ to be a constant length, but I've always followed that practice since my dBaseII days.

>The minus is a concatenation operator for 2 strings, but, it is different of the plus operator because it removes all trailing blank spaces from the first operand and put them back at the end of the result, thus the lenght of the result is the same as the sum of the to operands, I better leave english explanations and put code examples :)

HTH,
