A COBOL85 program can run at a low PIN under the D-series operating system
without any changes. However, for a program to use the extended features of the
D-series operating system, specific parts of it must be converted. The topics in this
section are:
Converting basic elements of a COBOL85 program, such as using the ZSYSCOB
file, declaring variables, calling Guardian procedures, and running the COBOL85
compiler
Converting a COBOL85 program to run at a high PIN
Converting a COBOL85 program to create and manage a high-PIN process
Converting a requester to communicate with a high-PIN server
Converting a server to communicate with a high-PIN requester
Section 8, “Converting Other Parts of an Application,” contains information about
converting other parts of a COBOL85 application. For additional information about
the Tandem implementation of COBOL85, refer to the COBOL85 Reference Manual.
