$DESCRIPTION$

     ALLTRIM() is a character function that removes both leading and trailing
     spaces from a string.  It is related to LTRIM() and RTRIM() which remove
     leading and trailing spaces, respectively.  The inverse of ALLTRIM(),
     LTRIM(), and RTRIM() are the PADC(), PADL(), and PADR() functions which
     center, left-justify, or right-justify character strings by padding them
     with fill characters.

$EXAMPLES$

       This example creates a string with both leading and trailing
	spaces, and then trims them with ALLTRIM():

	cString := SPACE(10) + "string" + SPACE(10)
	? LEN(cString)                     // Result: 26
	? LEN(ALLTRIM(cString))            // Result: 6

       cString = SPACE(10) + "" + SPACE(10)
       ? LEN(cString)                           // : 26
       ? LEN(ALLTRIM(cString))                  // : 6
