The system variable named HELPKEY$ is a four-byte string. The
value of HELPLEY$ is set by an Internet Basic program and subsequently used
by the Comet Help System. The HELPKEY$ value links a help message
to an Internet Basic program using the following key:
object name + HELPKEY$
This may be used as an alternative to the screen position/program
address method of linking a help message to a specific program.
For example, if your program sets HELPKEY$ to a value of "ABCD"
and your object program is named "PROG1234", the help message
will be keyed as follows:
You may change the value of HELPKEY$ throughout a single Internet Basic
program; each new value will effect a new help message link. This
is the way to link numerous help messages to a single object
program without using the screen position/program address method.
If the HELPKEY$ variable is not set by your Internet Basic program, the
system assigns it a null value, and the Comet Help System (if
invoked) will link help messages to the program as follows:
object name + screen position, or
object name + screen position + program address
