Is there anyway we can separate out the variables declared in main function from the variables declared outside the main function.. That is variables declared in other function definitions and in the global section..
I mean we need to store the variables declared in the main() in one file and the rest of the variables(including the global declarations) in another file..
Note the line numbers may not be in order..
Any idea??
Thanks in advance..

Hi all,

my $ENV{a}="20";
system("perl called.pl");
and my called.pl contains:

Hi,
I have a main loop which calls a sub loop, which finally returns to the main loop itself. The main loop runs when a flag is set. Now, I have a signal handler for SIGINT, which resets the flag and thus stops the main loop. Suppose I send SIGINT while the program is in subloop, I get an error... (1 Reply)

Hi friends,

H friends,
As we know, a function returns a value and that value is saved somwhere. like
int Sum( int x, int y )
{
return x + y;
}
Total = Sum( 10, 20 );
The value 30 is saved in variable Total.
Now the question is, what int value does the function main return, and where is it... (5 Replies)
A sample.c file is written with only one single statement.
main;
Segmentation fault occurred when executed that file.
Any statement other than main; is written, for example unix; then it won't compile.
why is this behaviour ! (2 Replies)

global
global(n) Tcl Built-In Commands global(n)
__________________________________________________________________________________________________________________________________________________NAME
global - Access global variables
SYNOPSIS
global varname ?varname ...?
_________________________________________________________________DESCRIPTION
This command has no effect unless executed in the context of a proc body. If the global command is executed in the context of a proc body,
it creates local variables linked to the corresponding global variables (though these linked variables, like those created by upvar, are
not included in the list returned by info locals).
If varname contains namespace qualifiers, the local variable's name is the unqualified name of the global variable, as determined by the
namespace tail command.
varname is always treated as the name of a variable, not an array element. An error is returned if the name looks like an array element,
such as a(b).
EXAMPLES
This procedure sets the namespace variable ::a::x
proc reset {} {
global a::x
set x 0
}
This procedure accumulates the strings passed to it in a global buffer, separated by newlines. It is useful for situations when you want
to build a message piece-by-piece (as if with puts) but send that full message in a single piece (e.g. over a connection opened with socket
or as part of a counted HTTP response).
proc accum {string} {
global accumulator
append accumulator $string
}
