global variables

[Naveen Garg]

I am trying to declare global variables from c.

However, the following fails: 

int parse_status;

eval_string("global gvar", false, parse_status);

I get: 

 error: eval: invalid use of statement list

It seems to work if i put 

global gvar 

in a file called file.m

and then run

int parse_status;

eval_string(source("file.m"), false, parse_status);

Also, I can come to terms with pass by reference only semantics.

But can't we at least get direct access to memory when using fortran_vec with get_global_value ? 

Octave is not multithreaded, whats the risk? 

Also, is there something akin to set_local_value (similar to set_global_value)? 

Thanks,
