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 statement accesses your C function in a 4GL procedure as part of the Host Language Call (HLC) interface that you run using an OpenEdge executable customized to access this function. 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:
