variable ../.. global

Show all headers | View raw

The man page of variable is in some things not very explicit.
I have some questions.

Question 1:

What is the difference between:

namespace eval foo {variable bar 12345}

and

namespace eval foo {set bar 12345}

Do not create both namespace variable?

Is "variable" about allocating space for the variable if there is
no value in the declaration?


Question 2:

I read "If the variable command is executed inside a Tcl procedure,
it creates local variables linked to the corresponding namespace
variables"

Does it also create the namespace variable? Or I need also to
execute it outside the procedure?


Question 3

I want to source a script, perhaps inside a name space, perhaps not,
and I want instead of global, variables only visible in the name space.

Is the solution to change "global var" with "namespace var"?

Thanks for any hint!

Rod.
