PRINTing score

[+Philsan]

In Basic, I would like to PRINT score variable right justified.

For example

SCORE   100
SCORE  1000
SCORE 10000

instead of

SCORE 100
SCORE 1000
SCORE 10000

Which is the best way?

The implied decimal place should line up, so the first way that you show is better.

 

But to provide a little "wiggle room," it might also depend on what else (if anything) would be printed on that same line after the score.

In Atari BASIC, use LEN(STR$(SCORE)) to get the size of the score. So, use something like:

POSITION 10-LEN(STR$(SCORE)),0
? SCORE;

But you must be sure that it will always increase, or you'll have to clean that space before updating, or use something like:

POSITION 0,0
? SPACE$(1,10-LEN(STR$(SCORE)));SCORE;

where SPACE$ is a string initialized with a given number of spaces, at least 9 in this example.

 

The first method should work in the latest verisions of Fastbasic, but for the second one, the method to get a substring is different from Atari Basic, and the bracket operator should be used:

POSITION 0,0
? SPACE$[LEN(STR$(SCORE))];SCORE;

But for scores higher than 9999 you probably need to use a floating point score variable SCORE%, or limit it to 4 variable digits and a fixed multiplier string (adding "0" or "00" at the end of the print).

Thank you very much Victor!

 

The first example works with FastBasic.

 

In my game score always increases and I will add "00" at the end of the print.
