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.
