Re: clearing global variables

[Michael Johnson]

Thanks Dmitri,

Unfortunately that didn't work:
octave:1> global VAR = 1;
octave:2> clear VAR
octave:3> global VAR = 0;
octave:4> VAR
VAR =  1

Here's a lame workaround that I came up with - included for the archives.

octave:1> global VAR; VAR = 1;
octave:2> clear all
octave:3> VAR
error: `VAR' undefined near line 3 column 1
octave:3> global VAR; VAR = 0;
octave:4> VAR
VAR = 0

So, for future reference, does this list expect people to be using the development code (aka 3.3.52). If so, is there a plan for an official release soon? I deliver octave simulations to customers who are unwilling or unable to compile octave themselves.

Mike

I suspect in your version of octave "clear" does not interpret "all"
as a special keyword and instead is trying to clear variable with
name "all". It has been fixed in later version. It works as expected
on octave 3.3.52+ on my computer.  You can do
"clear VAR" as a workaround.

Sincerely,

Dmitri.
