How can you pass values from COBOL program to non-COBOL programs

If u want to pass values from jcl to cobol use "parm" parameter in the exec statement and in the cobol program declare the linkage section for the values to be passed.If u want to pass values from cobol to other non-cobol programs this can be done by call by reference or call by value.ex: call pgma using ws-name, ws-sex.
