Create a variable

[Natter]

Hi,

To create a variable, I can write, for example: LOCAL AAA
Is it possible to create such a variable programmatically ?

[Antonio Linares]

Yes, but it won't be local

Simply assign it. At the top write:

memvar MyVar

later in your code:

MyVar = ...

but it will not be local, it will be public

Thanks Antonio, but this is somewhat not what I need. For example, I need to make 10 variables

for st=1 to 10
create variable "n_"+ltrim(str(st))
next

Perhaps,

for st=1 to 10
cName:= "n_"+ltrim(str(st))
PRIVATE &cName
next

Maybe better use a array ?

Local aGallery := ARRAY(12) // Max = 12 items

is very easy to programmaticaly fill these with specific data in a loop

for i = 1 to len(aGallery)
aGallery = i // or any dbf value or .....
next

You only have to think of 1 var name .... (Local of public,...)

You maybe also consider using Hashes (I prefer them)

No.
Because, the local declarations must be available to the compiler.

Ofc, you can create private variables at runtime.

Thank you, Rao !

Dear Yuri,

This is another possible way:

Code: Select all | Expand

#include "hbclass.ch"

function Main()

   local oVars := TLocal(), n

   for n = 1 to 10
      __objAddData( oVars, "n_" + LTrim( Str( n ) ) )    
   next
   
   oVars:n_1 = 123
   ? oVars:n_1

return nil   

return nil

CLASS TLocal

ENDCLASS

Thank you very much for an interesting opportunity !

Hello,

May I ask, what is the purpose of these variables?
Best regards,
