Compiling With Saved Global Data

During program development or maintenance, you often need to change procedural

code or data without changing the global declarations. You can save the global data in

a file during a compilation session and then use the saved global data during a

subsequent compilation. You can shorten the compile time by not compiling global

declarations each time. For more information, see Saving and Using Global Data

Declarations on page 17-8.

Using the Code Coverage Tool

The Code Coverage Tool evaluates the code coverage provided by application test

cases. The tool uses information provided by a specially-instrumented object file to

produce a report that indicates which functions and blocks were executed, and how

many times each was executed.

Using the Code Coverage Tool requires a special compilation to produce an object file

containing the required instrumentation. To create such an object file, specify the

CODECOV directive in the compiler command line.

For details on using the Code Coverage Tool, see the

Code Coverage Tool Reference

Manual.

Note. This topic applies only to the pTAL compiler. If you are using the EpTAL compiler, see

Migrating from TNS/R to TNS/E

on page 17-11.

Note. The Code Coverage Tool is intended for data generation and collection in a test

environment only. The use of instrumented object code is not recommended for production

environments. Applications compiled with code coverage instrumentation will experience

greatly reduced performance.
