String Concatenation

[toddtmw]

Okay. I know I’ve programmed in many many (too many to count) languages since my Atari days, but I simply do not recall how poorly Atari concatenates strings. Is there really no

A$=B$+C$

type functionality in Atari basic?

 

Is the “best” approach really this clunky?:

A$=B$
A$(LEN(A$+1)=C$

 

I do do not recall having to code this “badly” BITD...

Atari basic is a bit clunky with strings, although I believe Microsoft Basic can deal with addition of strings (never used it so can't confirm personally)

 

I've just started using FastBasic and would highly recommend it, although it still has the same problem with normal strings.  However, you can have variable strings with a max length of 255 which you can perform operations on.

Yes, really that complicated. Except that you have a bracket missing.

A$(LEN(A$)+1)=B$

I must not have done much string handling in my Atari days. Either that, or I blocked it out after I found other languages that did it so much better....

On FastBasic, you can do  A$ =+ B$  to copy B$ at the end of A$. I did not implement the easier to read " A$ = A$ + B$ " because it would need a temporary string (being slower), and normally you need just to concatenate and not to create an arbitrary string.

 

Have fun!

Toddtmw,

Perhaps back in the day you did something like this (assuming your string was large enough to support it and you already knew how long A$ was):

A$(x,x)=B$, where X is the index of the last character in A$. Doesn't seem so clunky to me. Just requires more direct knowledge of how your strings are configured.

Is B$ a single character in length?

Clarity.

It all seems clunky until you realise the limitations of orthodox string handling like 256 character limit and inability to do things like memory moves and using strings for playfield or PM graphics.

[Kyle22]

X=USR(ADR(ML$), [passed data], [passed data].

There is no 256 character limit to most Atari BASICs.

F**k it was one character from perfection :)
