HELPKEY$

 
System variable:  HELPKEY  
Length:  4  
Description:  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: 
  "PROG1234ABCD"

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 addres
