I encountered this error when running a script that had been running, but that I heavily modified.

I got is down to the following 4 lines:

#!/usr/local/bin/expect
puts "Enter 'hi', then ENTER"
expect "hi\n"
puts "buf: $expect_out(buffer)"

When I type in "hi\n", the 'puts' works OK
When I let it time out, I get this error:

can't read "expect_out(buffer)": no such variable
   while executing
"puts "buf: $expect_out(buffer)..."
   (file "trm22" line 4)

I can't see what's going on.
I'm running expect version  5.7.0 on a UNIX system.

Any help would be appreciated.

Thanks,
            Andy


Hi, Andy .. I've NOT got my expect stuff with me but I'm wondering if you try typing in something before "hi" do you get that reported back?    What if you do an
   array names expect_out
... what do you see?

I added that line to make it look like this

#!/usr/local/bin/expect
puts "Enter 'hi', then ENTER"
expect "hi\n"
array names expect_out;
puts "buf: $expect_out(buffer)"


That gave me the following error:

Enter 'hi', then ENTER
anb hi def
"expect_out" isn't an array
   while executing
"array names expect_out"
   (file "/home/scharmer/expect/trm22" line 4)

It looks like I can't look at expect_out(...) at all.



Hmm ... think you have your threads mixed??   I've posted a quick thought on the other active thread ...
