It is spawning a child process to run the SendToLogs.pl
script with a  
set of arguments.

It will wait until the script completes before continuing
execution.

It would be as if you had typed

% SendToLogs.pl -msg "Check ServerConnection checked
ok." -appname  
checkServerConnection -level 2

at the command line.

I can't tell you what SendToLogs.pl does; for that you'd
need to read  
it.

And it returns the completion code back to the caller.. If
you want
the output of the command (e.g. date), I use the back tick
as in below:

$cur_date = `date`;

flk k
