Answer / smijo
incase u redefine X(9) to 9(9).. and if value of x(9) is 'AAAAA' , then if you display the redefined numeric variable it will also show 'AAAAA'. so to check the numeric variable actually contains numeric data like 9999 you can use IS NUMERIC.
if X(9) contains 999999999 then ur if variable is numeric will be true
