Does anybody have code for this?,

I'm doing a 16-bit (DOS) C program for reading a file with 2 fields pipe separated, and show them like

Key     Des
    1     One
    2     Two
    3     Three
and so on

I want to know how i can "scroll" the list if i've got more lines that maximum i can display at once.
Thanks

If you want to make a plain terminal-style app, just put a message every 24 lines:

printf("Key\tDescription\n");
for (int i=0; i<maxElement; i++)   /* assuming some variable names */
{
         if ( (i+1)%24==0 ) {
              printf("Press any key to continue...");
              getch();
              printf("\n");
         }
         printf("%i\t%s\n", i, yourArray[i] );
}

If you want a more sophisticated user interface, use console functions that Turbo C gives you.

good luck,
Jaime.

Sorry, there are many years since I stop developing in Turbo C (about 15), but all information is in Turbo C Help.
See help about <conio.h> funtions.

You could always just pipe the output to the MORE command on DOS.
