No there is not, why not to declare NUMERIC value with the maximum number of digits it may have....If you dont know that...give Maximum...

From Manuals FYI...

Hi PK,

You can define a DB2 varchar host variable in COBOL like this:
Code:

05  your-data.
    49  yr-data-len  pic S9(4) comp.
    49  yr-data-txt  pic  X(25).


The len contains the length of the string in txt. You then use a refmod move to extract the string.

E.g. move yr-data-txt(1:yr-data-len) to some-where
