CALL Statement

Transfers control to a dispatch routine (PRODSP) that then calls a C function. You write the C function using ABL Host Language Call (HLC) interface.

ABL HLC consists of a collection of C functions that:

Obtain data from ABL shared variables and buffers
Set data in ABL shared variables and buffers
Control screen modes
Provide ABL-like messages in the message area at the bottom of the screen

Using HLC, you can extend ABL with your own C functions.
