Look at the DATATYPE function.

It's a TSO (or IDCAMS) command. Allocate. "Allocate storage to the DD name XMITNOTE reusing any current allocation with a disposition of NEW and CATALOG".

Hi,

I went through it..........Binary can be identified......but i am confused how REXX will differentiate between alphanumeric(having numbers),characters(storing number),PD,ZD...etc.

review Your understanding of REXX objects,
everything is a string,

why not run Yourself a few tests ....
Code:

say "datatype('ABCDE')   is :" datatype('ABCDE')
say "datatype('12345')   is :" datatype('12345')
say "datatype('123.45')  is :" datatype('123.45')
say "datatype('0123c'x)  is :" datatype('0123c'x)

an read the manual

REXX will not directly give you this. . . Also, i do not understand what these "alphanumeric(having numbers),characters(storing number)" mean?

If you were able to get the "cobol" field-type, how would it be used?
