Hi

I am quite new to expect
I have a problem in hand

I am setting  a variable xyz  to a certain value say 85 in a procedure1  that is executed on machine1

.Now i want to use this value in another porcedure2 after i logon on to another machine2 through expect .

But I am not able to do it

What i am doing currently is That I am setting a variable
set xyz " "  
in the begining

then using it in procedure 1 on machine1 by declaring  it as  global  and then assigning it a value there.

and then using it in procedure 2 on machine 2
but xyz doesn't shows up with the value 85 there
?

Am i using the write procedure for using and setting  the variables

Thanks in advance





If you declare a variable to be global in a proc in tcl (or expect) then that variable is the same as the variable of the same name in the main program that you're running.   So if you declare a variable to be global within two different procs that are running as part of the same program, they're one and the same.

However, global variables are only shared within a single program - it doesn't REALLY mean "Global" in the real world sense.  You can't declare a variable as being global in program X running on computer Y and have it turn up in program R running on computer T somewhere else in the world.  I think that's in effect what you're trying to do - sorry - it just doesn't work like that.



Hi

thnx for the quick reply.

Can u please help me out by giving any other method  or any other way for doing  such a thing .




If I wanted to copy the contents of a variable from one machine to another when running two processes liked by expect, I would probably send the value as part of a string from the system on which it originated and expect it on the destination machine, saving it into a variable from [b]expect_out[b].

That's not a very friendly / maintainable / extensible option and if you have a lot of data involved and want it shared both ways, you would to better to look at storing and recovering data into a commonly accessible location such as a MySQL database or even on a website.
