Binding COBOL code to the IMS language interface module
IMS™ supplies a language interface module (DFSLI000). This module must be bound to the batch program after the program has been compiled. It gives a common interface to IMS.
If you use the IMS-supplied procedures (IMSCOBOL or IMSCOBGO), IMS binds the language interface with the application program. IMSCOBOL is a two-step procedure that compiles and binds your program. IMSCOBGO is a three-step procedure that compiles, binds, and executes your program in an IMS batch region.
