SET FUNCTION <n> TO 'a;b'

[alcz]

SET FUNCTION <n> TO that contained ';' characters were translated to <Enter> in Harbour 3.0 (Clipper compatible behaviour)

#include "inkey.ch"
MEMVAR GetList
PROCEDURE Main
   LOCAL a := "  ", b := "  "
   hb_gtReload( "TRM" )
   SET FUNCTION 5 TO "a;b;"
   hb_keyPut( K_F5 )
   @ 1, 1 GET a
   @ 2, 1 GET b
   READ

In current Harbour 3.2 it just inserts those ';' semicolons. You can spot the difference in playground too.

I'll take a look at this one later if nobody knows the cause.
