Preparing to link-edit and run under Language Environment

This topic discusses what you need to know before link-editing and running applications under Language Environment. After Language Environment is installed on your system, you should run an existing application under Language Environment. Although you may need to link-edit to different libraries, the procedure is similar to that used in pre-Language Environment versions of C, COBOL, Fortran, or PL/I. For more information about running applications under Language Environment that have not been linked with Language Environment, see the for more information.

To help you get started, this topic describes the following common link-edit and run tasks, which you might want to try before reading further:

Link-editing and running an existing object module and accepting the default Language Environment runtime options
Link-editing and running an existing object module and specifying new Language Environment runtime options
Calling a Language Environment service

Note that several Fortran and C library routines have identical names. This topic describes what you must do to resolve any potential conflicts in using these names.

This topic also describes basic tasks intended to help give you an idea of what running an application under Language Environment is like. It is not intended to illustrate every aspect of link-editing and running you might want to learn. Detailed instructions about link-editing and running existing and new applications under each supported operating system are provided in other topics in this information, and in z/OS MVS Program Management: User's Guide and Reference and z/OS MVS Program Management: Advanced Facilities.
