You may use nRandom( <nRange> ) --> nValue to create random numbers.

Try the folowing:
Code: Select all
FUNCTION Unique()
LOCAL cNumeric:= STR (HB_RANDOMINT(1,10000) ,5)
// You may use any number instand of 10000
cNumeric := STRTRAN (cNumeric ," ","0")
RETURN( cNumeric)

Hello Silvio again
Try the following :
Code: Select all
FUNCTION Unique(nTotale)
RETURN( HB_RANDOMINT(1,nTotale))
