To use this very first version, you must install the Navigator 0.01 library in any port of your HP49G.

Then, two possibilities :

• Online use, if you own an external modem, then you can try to build an HP-modem adapter and connect the HP to internet using Usinagaz 0.19.

  In that case, you need, in addition to Usaingaz's own parameters, to define 4 variables :
  - Connexion : program to launch to start the internet connection through the modem
  - URL : internet adress with which to begin the connection (note that at the present time you can't type in a new URL while the program is running, you must stop Navigator with ON and manually modify URL).
  Example : "http://www.hp-sources.com/navigator/index.html"
  - Domain : domain name. Example : "www.hp-sources.com"
  - Path : current path. Example : "www.hp-sources.com/navigator/"

  Once those parameters are defined, you only have to connect with the HP49 (good luck to write the Connexion proram, you'll have to adapt to your modem...) and launch NAVIGATOR to surf from the specified page.



• Other possibility : offline use.

  You need in that case HTML pages stored in HOME and/or its subdirectories. Furhermore, the links have to be relative ones. In case of absolute link, Navigator will try to launch the connection executing the Connexion program that you have stored in HOME. Put then a string containing an HTML file at stack level 1 to display it. If no object is on stack level 1, or if stack level 1 is no string, Navigator lauches the filer and invites you to select an HTML file and open it (OPEN icon).

Navigator 0.01 is only a first version, and all its bugs have not been fixed, by far. Some HTML files make the HP badly bug, so backup your RAM before... Try not to put the HP in low memory condition, because this induces frequent Garbage Collections during the execution, and Navigator doesn't like Garbage Collecions... It is so quick to flare up.

Keys :

• Up and down arrows : vertical text scrolling.
• ENTER in text mode : to go (irreversible) to link selection mode. The first link of the page is then video inversed.
• ENTER in link selection mode : "clicks" on a link. Navigator goes then to the page at the end of the link.
• Left and right arrows : in link selection mode, moves from a link to another.
  Beware, the video inversion can go out of the screen (the screen will be readjusted in the next versions).
• Red shift then vertical arrows : to access the beginning or the end of the text.
• S key (speed) : toggles the scrolling speed : once to accelerate, a second time to go back to low speed.
• ON : ends the program.
