Many Deskshell and UNIX commands perform an action and print a result. You can trap the output of such a command, and use it in a Deskshell script, with the `{...} construction.
The text output from the command is split into a list of strings at the character specified in $ifs(1), or the characters space, tab or newline if ifs is unset.
For example:
size=`{ls -s $1}
assigns the string representing the size and name of the file
$1 to the variable size.
