GOAL:

Example of a C program using HLC

FIX:

1) Copy the following files from the $DLC/probuild/hlc directory into your working directory:

hlc.h, hlprodsp.c, and c


2) Add the definition of the HLC function "HOLA" into hlprodsp.c to look like this:


#define FUNCTEST(nam, rout) \
if (strcmp(nam, pfunnam) == 0) \
return rout(argc,argv);
long PRODSP(pfunnam, argc, argv)
char *pfunnam; /* Name of function to call */
int argc;
char *argv[];
{
FUNCTEST("HOLA",mytest);
return 1;
}


3) Create a file called mytest.c with the following c code:


#include "hlc.h"
int mytest (int argc, char *argv[]) {
promsgd("Hello World");
return 0;
}


4) execute the Progress script $DLC/probuild/eucapp/buildenv

5) Compile the hlprodsp.c and mytest.c programs using the following command:

./c *.c

This must generate the hlprodsp.o and mytest.o object files.


6) Execute probuild

7) In the first screen that reads "Install Link Script Into:" just select "<continue>"

8) In the "PRODUCT LIST" select "PROGRESS CLIENT" and press <ENTER>

9) Leave the default names for link scripts and select "<Continue>"


10) In the "CONFIGURABLE ELEMENTS" select "TCP-IP NETWORK PROTOCOL" and "HLC" then select "<Continue>"

11) In the "OBJECT FILES" screen, type hlprodsp.o and mytest.o and press "<Continue>"

12) Exit from Probuild by pressing <F4> twice.


13) Execute the script ldpro, this will generate an _progres executable. There must be no error messages or warnings.


14) Set the the environment variable PROEXE to point the new executable.

Example: PROEXE=/usr/hlc/_progres; export PROEXE

15) To test the HLC function with the following 4GL command:


CALL HOLA
