PPL PRINT Function
I am on my third day with my new Prime, and I'm loving it.

To try out PPL for the first time, I entered one of my favorite programs - how many ways to make $1.00 from change. It's a simple set of four nested FOR-NEXT statements with a test in the middle for whether or not the current combination of pennies, nickels, dimes and quarters add up to 100.

In the middle, I like to also print out those combinations that add up to 100. Usually, something like this: P: w N: x D: y Q: z all on one line for each combination.

I have not yet found how to make the PPL PRINT function print anything more than one thing on a line, so I am getting this instead:
P: w
N: x
D: y
Q: z

This is not very display friendly as everything is run together vertically.

Can anyone tell me how to PRINT more than one thing on a line?

Code:
EXPORT Dollar()
BEGIN
PRINT();
C:=0;
FOR P FROM 0 TO 100 STEP 5 DO
FOR N FROM 0 TO 20 DO
FOR D FROM 0 TO 10 DO
FOR Q FROM 0 TO 4 DO
IF P+(N*5)+(D*10)+(Q*25)=100 THEN C:=C+1;
PRINT("P:" +P);
PRINT("N:" +N);
PRINT("D:" +D);
PRINT("Q:" +Q)
END;
END;
END;
END;
END;
MSGBOX("ways_to_make_a_dollar="+C)
END;

Thanks very much, in advance, for your patience and advice.

RE: PPL PRINT Function
One way to do it (click in terminal screen to end, or wait for timeout):

Code:

EXPORT Dollar()
BEGIN
  PRINT();
  C:=0;

  FOR P FROM 0 TO 100 STEP 5 DO
    FOR N FROM 0 TO 20 DO
      FOR D FROM 0 TO 10 DO
        FOR Q FROM 0 TO 4 DO
          IF P+(N*5)+(D*10)+(Q*25)=100 THEN C:=C+1;
//PRINT("P:" +P);
//PRINT("N:" +N);
//PRINT("D:" +D);
//PRINT("Q:" +Q);
          print("P:" +P + "  " + "N:" +N +"  " + "D:" +D + "  " +"Q:" +Q);
          END;  // ends if
        END;  // ends Q
      END;  // ends D
    END;  //  ends N
  END;  //  ends P

  wait(-1);
  return MSGBOX("ways_to_make_a_dollar="+C);
END;

RE: PPL PRINT Function
Thank you *very* much, DrD.

I had not yet figured out why the "+" was needed to get the second item into my PRINT statements, but now it makes perfect sense.

Thanks again for your patience and attention.
