<> Take a look at the string function (-help string_functions-) indexnot() (e.g., "gen x = indexnot(string1, string2)" ) which will give you the leftmost position where the two strings differ. This Stata string function does not assign the positive/negative sign like the sas function you describe, but you can code those yourself by using other string functions to find how they differ in order/sequence/length. - Eric __ Eric A.

It allows to compare strings. Specifically, in Sas COMPARE(string-1, string-2) returns a numeric value. The sign of the result is negative if string-1 precedes string-2 in a sort sequence, and positive if string-1 follows string-2 in a sort sequence. The magnitude of the result is equal to the position of the leftmost character at which the strings differ. > > Thanks! > > Jo > > * > * For searches and help try: > * http://www.stata.com/help.cgi?search > * http://www.stata.com/support/statalist/faq > * http://www.ats.ucla.edu/stat/stata/ * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
