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.
