I need to be able to display an "R", followed by inputing a decimal numberv within a logical program loop without entering a
caraige return ("\n") I would like the loop to repeat itself by entering a whitespace character (newline, tab or space), but exit the loop when I hit the enter key, then start again. The following shows the routine as I now have it:

printf("\n\nEnter resistance number\n");
for (i= 0; i < n1; i++)
{
printf("\nRow %d, : \n", i+1);
for (j= 0; j < maxsize04; j++)
{
rws1 = 30;
printf("R");
scanf("%u,%c",&rws1,&s1);
while ((rws1 < 0) || (rws1 > maxsize20) || (cra[rws1][1] !=
999))
{
if (cra[rws1][1] < maxsize20)
{
printf("\n%1d", cra[rws1][1]);
printf("\nToo Many Circuits for R Entry - Reenter ");
}
else
if ((rws1 < 1) || (rws1 >= maxsize20))
{
printf("\nR Out of Range - Reenter ");
printf("R");
scanf("%u,%c",&rws1,&s1);
}
}
if (rws1 == 0)
break;
cr[i][j] =rws1; //R to circuit array
if (rws1 > rmax)
rmax = rws1;
if (cra[rws1][0] > maxsize20)
cra[rws1][0] = i; //First circuit for this resistance
else
if (cra[rws1][1] > maxsize20)
cra[rws1][1] = i; //Second circuit for this resistance if ((s1 != 10) && (s1 != 13))
continue;
else
break;
} // {j}
} // {i}

I've tried using following the scanf instruction with a getchar() but that doesn't work either. Keying in a whitespace other than a newline (tab or space) doesn't advance the loop to print out an "R" followed by a scanf. "C" manuals have led me to believe that this would work, but it doesn't.

Just out of curiosity why don't you want to allow the use of the carriage
return after the user input?

Anyway try getch() instead. Please note though that getch() doesn't echo
the character to the screen, you'll have to take care off that...
