Autodeclare of variables

[Dmitry]

Basic is assumed as simply programming tool. But It is able to make serious projects.
I meeted some ugly feature. Im debugging complex project. In the head is twisting algorithm. Syntax is often looses. I simply can make syntax error in variable name. Wrong named ones allocates and uses as normal. When I have 64 bit of ram, its signifucantly by amount of space. And when project runs, I have very interesting effects ))))))))))
Im requesting to make such autoallocation optionally or even turn off at all. Where I can ask it?

try this:

#Option Explicit
Syntax:

    #option explicit
This option ensures that all variables are dimensioned in the user program. The scope is the user code only and no other code space like .h or include files.

#option explicit requires all variables,including bytes, in the user program to be defined.

Variables can be defined and not used within your user program. Unused variables will not allocate memory.

Introduction:

Example:

    'Set chip model
    #chip 16f877a

    'Example command
    #option explicit

    dim myuserflag as byte

    myuserflag = true
