PPL PRINT Function - smp - 07-26-2015 10:51 AM
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.

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);

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.
