sleep command for Expect
Lydie
I guess I can ask my expect question in this forum (maybe I am
wrong?).
In my expect program I need to execute the sleep command. In the
Exploring Expect book, it's written that the way to do that is just to
execute: sleep <#seconds>. So I did it. Unfortunately it failed.
Result: I need to use exec or system to do it. Is it a known problem?
Maybe it's not supported with the expect version I have (who knows?)
Version: 5.1.3.

Sleep works fine. I have never heard of any problem with it.
What platform (Linux/Unix/Windows) are you using? How does it fail? Can
you provide a code example?
Lydie
The platform is HP Unix.
Example of code: sleep 10 (like in Unix)
Error:
invalid command name: "sleep"
while executing
"sleep 10"
Could it be possible that the Expect interpreter on my system has been
modified? Is it possible? How can I check?

This version number is pretty unknown to me. The oldest one
I could find in my archive was 5.26, dated somewhere in 1997.
Are you sure you are running expect?
The "sleep" command is of course not implemented in Tcl --
maybe you didn't load the Expect extension? Try the command
package require Expect
in an interactive Tcl session and check the output (should
print a version number).

Well, that isn't much of a code example. I assume that the sleep
command is used in conjuncton with other Expect commands, such as send
and expect, and that the other commands work fine.
If so, and if you inherited the computer you are using, then your
guess about Expect being modified seems reasonable.
I just tried this test and it showed that sleep is a command available
to the interpretor.

Try loading the latest versions of TCL and Expect and see if the
problem is still there.
