Release 10.1A: OpenEdge Deployment:
Managing 4GL Applications

> ## Requirements

> To use a custom C function in the 4GL, you must invoke it using the 4GL `CALL` statement.

This appendix describes how to customize an OpenEdge executable to access a C function using the HLC interface. For more information on using custom C functions in the 4GL, see the Host Language Call Interface Web paper at:
