If your organization uses LANSA development tools, you should know that as of LANSA V12SP1, a set of built-in functions is available in the LANSA development environment that permit your LANSA applications to interact with LANSA Composer through the LANSA Composer Request Server.

The built-in functions are:

  • COMPOSER_USE : Specifies connection information for subsequent requests
  • COMPOSER_RUN : Runs a LANSA Composer Processing Sequence
  • COMPOSER_CALLF : Calls a LANSA function

The COMPOSER_RUN built-in function is for use in a LANSA application to execute a LANSA Composer Processing Sequence through the LANSA Composer Request Server.

The COMPOSER_CALLF built-in function is intended to be used in a custom activity processor that executes in the LANSA Composer environment.  It is to permit your custom activity processor to call a function in your LANSA application through the LANSA Composer Request Server.

Refer to the LANSA Technical Reference for detailed programming instructions for these built-in functions.

The LANSA built-in functions do not support connecting to a request server on a remote system.  They can only be used for integrating LANSA applications and LANSA Composer systems that execute on the same server system.
