The .HELP control variable can be set in the initialization section to establish a tutorial (extended help) panel to be displayed if the user enters the HELP command.
>>-.HELP--=--panelname-----------------------------------------><
>>-variable--=--.HELP------------------------------------------><
.HELP = ISPTE
This example causes tutorial panel ISPTE to be displayed when the user enters the HELP command.
The .HELP control variable can appear on the right side of an assignment statement, making it act like a function.
