You can specify entries for alphanumeric data items that contain DBCS or mixed characters, in the Linkage Section of the Data Division. If DBCS data items or DBCS literals are being passed to a program you can also define the receiving linkage section items as DBCS data items.
You can pass DBCS characters from one program to another program by specifying those data items in the USING phrase. USING BY CONTENT and USING BY VALUE, allows mixed and DBCS literals to be passed.
You cannot use DBCS characters in the CALL statement for the program-name of the called program. You cannot use DBCS characters in the CANCEL statement because they specify program-names.
