Choices to make now

First, decide which language-specific features you should modify for your site. For more information about the C/C++, Fortran, and PL/I features you can customize, see:

Using Fortran with Language Environment
PL/I for MVS & VM Compiler and Run-Time Migration Guide

You also need to choose which sample customization jobs you will need to modify and run. Table 1 lists the sample jobs provided on the distribution tape to help you customize COBOL, C/C++, Fortran, and PL/I features. These jobs are part of Language Environment sample library SCEESAMP.
