Accessing TCL from MV BASIC

Execute TCL safely and handle captured output, replies and selected lists

01

EXECUTE crosses from BASIC into TCL

EXECUTE evaluates an expression as a TCL command in the program's current session and account context. It is useful when an existing verb already performs the operation you need, when building an administrative tool, or when a BASIC program must create a TCL selected list. It is not a replacement for direct OPEN, READ and WRITE logic when the program already owns the data operation.
