need help converting old style def fn functions
#1
I'm playing with the code for an old game "Wizard's Castle" from 

https://www.ifarchive.org/indexes/if-arc...rce/basic/
\___ https://www.ifarchive.org/if-archive/gam...wizard.zip
        \___https://unbox.ifarchive.org/?url=/if-arc...wizard.zip

and am getting a "Subscript out of range" error on line 82: 
Code: (Select All)
1530 L(FND(1)) = 2

where function FND was originally 
Code: (Select All)
DEF FND(Q)=64*(Q-1)+8*(X-1)+Y

The DEF FN lines (42-46) were causing errors, so I tried converting them to functions (now at lines 949-975):
Code: (Select All)
Rem DEF FNA(Q)=1+INT(RND(1)*Q)
Function FNA (Q)
    FNA = 1 + Int(Rnd(1) * Q)
End Function

Rem DEF FNB(Q)=Q+8*((Q=9)-(Q=0))
Function FNB (Q)
    FNB = Q + (8 * ((Q = 9) - (Q = 0)))
    'FNB = Q + 8 * ((Q = 9) - (Q = 0))
End Function

Rem DEF FNC(Q)=-Q*(Q<19)-18*(Q>18)
Function FNC (Q)
    FNC = ((0 - Q) * (Q < 19)) - (18 * (Q > 18))
    'FNC = -Q * (Q < 19) - 18 * (Q > 18)
End Function

Rem DEF FND(Q)=64*(Q-1)+8*(X-1)+Y
Function FND (Q)
    FND = (64 * (Q - 1)) + (8 * (X - 1)) + Y
    'FND = 64 * (Q - 1) + 8 * (X - 1) + Y
End Function

Rem DEF FNE(Q)=Q+100*(Q>99)
Function FNE (Q)
    FNE = Q + (100 * (Q > 99))
End Function

but I must be missing something converting the math from this old QBasic or GWBasic (or whatever OLDE IBM BASIC it was done in) to QB64. 

Any help getting this to work would be most appreciated (code below). 

PS The program listing must use codepage 437 characters, I'm not sure how to get them to display properly in the forums editor, but it should paste into QB64's IDE correctly. I'll attach the file as well just in case...

I don't know if this will help you:

In this function X and Y will always be 0.

---------------------------
Function FND (Q)
FND = (64 * (Q - 1)) + (8 * (X - 1)) + Y

End Function
----------------------



not 100% sure it'll work but I'd recommend adding this line after the original source code line 1130:

Dim Shared x, y

Thanks, I think that may be it! 
It makes sense that those would be global variables with the old Def Fn.

Good. I looked like it would work. I just didn't fiddle with it long enough to see if something would blow-up in the game later.

That indeed fixed the problem - I haven't extensively explored the game yet. 
I'm more looking at the code to learn how some of the mechanics of old school RPGs worked. 
One fun mini-project I started is replacing the GOSUB and GOTO line numbers with descriptive labels. 
I ran tests on FNA FNB FNC FND FNE and generally figured out what they do. 
(One huge accomplishment Microsoft made with QuickBasic in my opinion was moving away from line numbers to structured programming.)
More to come...

Hi
very strange code

DEF FNB(Q)=Q+8*((Q=9)-(Q=0))
this function returns Q for all value of Q except for 9 that returns 1  and  for 0 that returns 8
Is it better using an IF THEN ELSEIF THEN ELSE  that seems less cryptic!

and this other
DEF FNC(Q)=-Q*(Q<19)-18*(Q>18)
it returns Q + 18 if Q>18  or -Q if Q<19

moreover
DEF FND(Q)=64*(Q-1)+8*(X-1)+Y
translated in Function must get X and Y to do a correct calculation
Dim Shared  versus Function parameters

and at last
DEF FNE(Q)=Q+100*(Q>99) 
this FN returns Q if Q <=99  and it returns Q-100 for Q value > 99

However creativity is the first tool of a programmer|

Indeed. 
I think this may have been created waaay back in the day, maybe in GW-BASIC or BASIC A?

The "DEF FN" assumes *all* variables are global, that's why it was eventually replaced with SUB/FUNCTION in M$QB. "DEF FN" has no way to declare a variable local, and not even to set its type. That's why when converting one of those to "FUNCTION" the programmer has to watch out for variables that weren't listed as parameters to the function. Also couldn't create a string function with "DEF FN".

Try compiling your code (which looks less than the spaghetti shown above) with "OPTION _EXPLICIT" at the top.

Good point, thanks. I always like to dim my variables at the top of the scope, a habit instilled in me in so many other languages!
