Referencing variables like handles

[johnnyd]

Hi good people,

Its been a while since I was here but still alive & kicking!

Is there a way of referencing variables the same way as you can do with handles?

Handles:

(5 textboxes: #main.1, #main.2, #main.3, #main.4, #main.5)

for a=1 to 5

    h$="#main."+str$(a)

    #h$,str$(a)

next a

so 5 textboxes are filled with the incrementing value of a.

So with variables:

aa=1

bb=2

cc=3

dd=4

ee=5

vars$="aa,bb,cc,dd,ee"

for a=1 to 5

    h$=word$(vars$,a,",") ;get the variable name from a list

    #h$,[new value]         ;give it the new value

next a

so the variables have changed: aa=2, bb=4, cc=6, dd=8, ee=10

This would make changing variable values much easier and the code shorter if there are numerous variables you want to change in one go, as in a for/next loop

I know dimensioned arrays is one way to do this by referencing the array elements, but how memorable & meaningful are these when you're coding?!? If you have e.g. a 50 x 50 array, you have to know exactly what each row & column is for, especially when debugging and trying to follow the changes. As the variable name is referenced directly, you can track them easily.

Just a thought!

How about giving the array() indexes meaningful names.

Z=array(Object,Ypos)

Xpos, Ypos and Zpos for example can be global,defined at the start. As 1,2,3

I think we need a better explanation of what you are trying to do.

Here is how one would evaluate a variable from a list of variables in a string separated by commas such as you show. Is this what you are asking?

aa=1
bb=2
cc=3
dd=4
ee=5

vars$ = "aa,bb,cc,dd,ee"
For i = 1 To 5
   Print Eval$(Word$(vars$, i, ","))
Next i
