By default, the helpfile \cbase\lib\cbase\help\form is accessed by form(C-1)
whenever the HELP key or the key sequence <F1> H is typed. If there
is a file with the same pathname as the formfile with a .h appended,
this helpfile is used for displaying help information. Customized helpfiles
have been created for each of the formfiles in the C/Base demonstration system.
You can examine them for examples of customized helpfiles.
