Executing a command named in a variable

[Ray Parrish]

Hello,

I'm thinking of a way to set a default external editor in a bash program 
I am writing, and need to know if it is possible to execute a command 
named in a variable that gets set by retrieving the command line for the 
external editor's command line from a configuration file.

Would the following work?

# set variable to command line
ExecuteEditor="/usr/bin/gedit filename.ext"
# execute external command.
$ExecuteEditor &

If this does not work, is there any other way to retireve the command 
line of an external command and run it?

Thanks, Ray Parrish
