For a varchar data item , the following declaration is used.

01 A.
49 ws-len pic s9(4) comp.
49 ws-text pic x(3).

my query is how does ws-len get the value ? is it passed via parm in jcl , or do we pass it in cobol pgm ?

Thanks

when the var char column is to be updated or inserted via sql,
the length must be populated prior to execution of the sql.

DB2 will populate the length during a Select operation.

Yes for DB2 it's as you said . But in simple COBOL pgm for a varchar declaration , how would the length be populated ?

Hello,

If level 49 is used, it is a db2 item (unless some mistake has been made).

The way a working-storage field of varying length is defined is usually with an OCCURS DEPENDING ON.
