Hi,

It is possible to have dynamic arrays in Clarion but there is some limitations. The array can't be a global variable (i.e. : it has to be in a routine or a procedure.) I do it like that :

Method 1 :

I fisrt declare a global variable in my procedure

DimArray Long

Then in a routine :

DynArrayRoutine Routine
Data
DynArray LONG,DIM(DimArray)
Code

Loop i# = 1 To DimArray
DynArray[i#] = i#
message(DynArray[i#])
End

Method 2:

In the global data of the program

DimArray Long

Then in a procedure :

DynArrayPROC PROCEDURE ! DynArray LONG,DIM(DimArray)
CODE
Loop i# = 1 To DimArray
DynArray[i#] = i#
Message(DynArray[i#])
End

The dimention has to be initialised before to call the Routine or the procedure.

Hope this will help you.

Valery.
