It is a really bad idea. It is extremely insecure, dangerous, error-prone(not just malfunctioning but syntax errors out of the blue given unexpected input), difficult to pass values into and out of, and incomprehensible to anyone who didn't write it (and often enough, to the writer, eventually).

Wanting to do so usually means more ordinary methods like functions, variables, and loops have been overlooked.

What exactly is your goal here? What problem are you trying to solve by storing commands?

ns_log

ns_log(3aolserver)					    AOLserver Built-In Commands 					ns_log(3aolserver)

__________________________________________________________________________________________________________________________________________________

NAME

       ns_log, ns_logctl - commands

SYNOPSIS

       ns_log severity message
_________________________________________________________________

DESCRIPTION

	While the AOLserver is running it logs various events from Notices to Fatal errors. Usually the AOLserver is running in the background, in
       which case these messages are placed in the server log. In absence of an ServerLog key in the AOLserver nsd.ini	file,  this  file  is  the
       /log/error.log  under  the AOLserver installation directory. When the AOLserver is running in the foreground the messages are redirected to
       stderr.

       ns_log writes the message to the server error log file. Allowable values for severity are:

       Notice - Something interesting occurred.

       Warning - Something that could mean something bad occurred.

       Error -	Something bad occurred.

       Fatal -	Something extremely bad occurred. The server will shut down after logging the message.

       Bug - Something occurred that implies that there is a bug in the code.

       Debug - If the server is in Debug mode, the message is printed. Debug mode is specified in the [ns/parameters] section of the configuration
       file. Otherwise, the message is not printed.
