Dynamic variable names in PureBasic?

What I mean is where the variable names are generated based on something like a counter. Something like this:
Which would create 10 variables:
Code: Select all
var_1 = 1
var_2 = 2
...
var_10 = 10
Is this possible? Thanks!

No, you can't do that with a for loop, but you can do it with macros. They are pretty useful.
The only downside is you have to run the macro for each new variable.

Yes, you can use Runtime:
Code: Select all
Define var1, var2, var3
Runtime var1, var2, var3
For i = 1 To 3
SetRuntimeInteger("var"+i, i)
Next
Debug var1
Debug var2
Debug var3

I never understand the sense of this kind of programing.
Why not using arrays?

Wow, that one slipped by me in all of the module excitement!
But why not use an array, as icesoft said?

Thanks everyone for the replies, these are great!
I was trying to figure out a way to initialize a variable number of nested Lists/Arrays that are supplied by argument to a Procedure, and could be referenced after creation (by the generated variable names). I could not figure out how to do this except for using a For loop to initialize the Lists/Arrays where the iteration # of the loop is appended to a common variable name.
I'm probably thinking about this all wrong, so if you have any suggestions they would be very much appreciated.

Maybe start with structures and combine the required variables in them.
Code: Select all
;-TOP
Structure sDataSet
iVal1.i
iVal2.i
fltVal.f
sVal.s
EndStructure
Procedure InitDataSet(*Data.sDataSet)
*Data\iVal1 = 1
*Data\iVal2 = 2
*Data\fltVal = 0.0
*Data\sVal = "Hello World"
EndProcedure
Procedure AddDataSet(*Data.sDataSet, iVal1, iVal2)
*Data\iVal1 + iVal1
*Data\iVal2 + iVal2
*Data\fltVal = *Data\iVal1 * *Data\iVal2
*Data\sVal = "Result = " + StrF(*Data\fltVal, 2)
EndProcedure
Procedure OutputDataSet(*Data.sDataSet)
With *Data
Debug "iVal1 = " + \iVal1
Debug "iVal2 = " + \iVal2
Debug "fltVal = " + \fltVal
Debug "sVal = " + \sVal
EndWith
EndProcedure
Global MyData1.sDataSet
InitDataSet(@MyData1)
OutputDataSet(@MyData1)
AddDataSet(@MyData1, 10, 5)
OutputDataSet(@MyData1)
