6 Converting Pascal Applications
096047 Tandem Computers Incorporated 6–1
A Pascal program can run at a low PIN under the D-series operating system without
any changes. However, for a Pascal 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 Pascal program, such as using the PEXTDECS,
PASEXT, and ZSYSPAS files, declaring variables, calling Guardian procedures,
and running the Pascal compiler
Converting a Pascal program to run at a high PIN
Converting a Pascal program to create a high-PIN process
Converting a requester to open and communicate with a high-PIN server
Converting a server to be opened by and communicate with a high-PIN requester
Section 8, “Converting Other Parts of an Application,” contains information about
converting other parts of a Pascal application. For additional information about the
Tandem implementation of Pascal, refer to the Pascal Reference Manual.
