How to Clear variables

[Gamiz Ribelles, Sergi (Regsa)]

I know, I ought to know how to clear (erase) variables, but I can't find it. I want to clear the variable itself not only its content.

please, any help

Thank you

Sergi,

 

I don’t think you can clear a variable from memory in MapBasic.  I’m pretty sure the allocated memory is released when the sub procedure completes (or module if it is defined outside of a sub procedure).  I assume global variables remain in memory until the program terminates. Perhaps someone with a bit more knowledge might be able to clarify whether this is the case or not; I’m working off assumptions here!

 

HTH,

You'll want the UnDim feature. 

UnDim x

That should do it :)

The caveat here is that this cant be used in a compiled mbx.  I'm curious about why you want to delete a variable.

Of Coooooooooourse: UnDim!!!!!!!!!!

In MapBasic Reference Guide, t the end of DIM Statement description, there is the seccion "See also" where doesn't appear "UnDim"

 

Erin: I needed UnDim statement because I wrote in the past a litle tool that define some variables and I'm using it recursively.

Sounds like you've dim'ed some variables at the wrong scope.   Move the appropriate Dim statement(s) into the routine called recursively.
