'HTML Viewer - Ian Smith - ian@isis.demon.co.uk - PB 3.2
'I regard it as PD, so feel free to do with it as you wish...
'
'Written to view HTML docs, select links and, optionally, put the
'URLs for those links into a script for collection.
'
'Use: hv <htmlfile> (.htm suffix not required, but if the suffix is
'                    anything other than .htm the suffix *is* required.)
'
'Keys: Home        - go to top of file
'      Up arrow    - move display up one line
'      Down arrow  - move display down one line
'      End         - go to end of file  
'      Page down   - move display down one page
'      Space bar   - ditto
'      Page up     - move display up one page
'      TAB         - jump highlight to next link
'      Enter       - save URL from highlighted link
'      Esc         - Exit
'
'History:
'HTML decoder was inspired by the  V3.07 one in the ABC collection,
'written by Toshigiro Horie.
'Converted to PB and modified to pull URLs from the page.
'That was a long time ago...
'
'Small memory model with minimal string allocation to run under
'YAN 1.3 (KA9Q). Speed traded for size....
