FHELP is a Host task which provides the user with IRAF like Help pages for FTOOLS. Users of the stand-alone Host version of this task automatically have access to a collection of ASCII formatted help files that are distributed in the ~ftools/ftools/help/ directory (for VMS, ftools:[help]) of FTOOLS. FHELP is a perl script unless perl isn't installed at your site, in which case, FHELP is a compiled FORTRAN program. Type 'fhelp fhelp' to get going. FHELP presents the task help a page at a time. If you are using the Perl version of fhelp, the output will be sent through your system's ``more'' utility (``type/p'' on VMS). If you are using the compiled fhelp, pressing y<return> pages the help file, pressing n<return> quits the display of the help file.
