Hi,
how to check whether the data type of a variable is numeric.If it is a numeric it has to print "valid data" or else print "invalid data".
how to check this?

Thank you!!!

Hello,

Are you using assembler or pl/i?

I believe you want to check the content of some fields for numeric values (rather than trying to check the "type" of the fields).

Hi,
I myself got the answer.
we can use VERIFY(var1,var2) built in function.
Ex:
var1=6788;
var2=0123456789;
VERIFY(var1,var2) will return 0.
if var1 doesnt contain any character that is in var2 then it returns a non zero value.

Thank you!!!!!

Bhagyalakshmi.... good that you found your answer but.....

Ex:
var1=6788;
var2=0123456789;
VERIFY(var1,var2) will return 0.
if var1 doesnt contain any character that is in var2 then it returns a non zero value.

the explanation you have given is wrong. it goes like this

:

if var1 does contain a character which is not in var2 then that function would return a non zero value
