- Changes as of revision 2.5:
-
- New features (lots!):
-
- Now checks for "LINES" or "WIDTH" environment variable set, truncating the
- compartment bar graph appropriately (for those of you who simulate DEEP
- dives :-))
-
- New option, -P, displays compartments as absolute pressure instead of
- tissue loading %age. The pressure is in <units> sea water absolute, where
- <units> is whatever units have been specified with the -u option. Default
- is feet. -P also causes the compartment values logged to an optional log
- file (specified with -l) to be in absolute pressure instead of loading
- %age.
-
- Graph can be toggled between loading display and absolute pressure
- display by pressing the 't' key WHILE THE PROGRAM IS CALCULATING, not
- while it is wating for input. For example, if you are running interactive
- and you enter a depth of 100 ft for 20 minutes, 't' can be used while
- the 20 minutes are elapsing to toggle the screen. 't' does not affect
-
- initial -P option.
-
- Changed the transition depth between bottom time and surface interval
- counting to 3 feet from 5 feet. This was necessary for decompression
- stuff (more later).
-
- 'q' can be pressed during calculations to abort the calculated run.
- For instance, when calculating a long decompression in autodecompression
- mode (more on this later), you can press 'q' to return to the input
- prompt. Similarly when calculating a long depth/duration combination
- entered from the keyboard.
-
- No Decompression Limits are now displayed and continuously updated along
- side the dive profile for each depth displayed.
-
- When NDLs are exceeded, the stats line now displays a ceiling, and a
- time to surface assuming proper following of the ceiling in 5 foot stops.
- For example, after 20 minutes at 200 feet, the stats line might display
- "Ceiling: 75.0 ft Time to surface: 46 min", indicating that the diver
- should not go shallower than 75 feet. If the diver makes decompression
- stops every 5 feet (stopping at each stop until the ceiling goes up to
- the next 5' stop), it will take 46 minutes to make it safely to the surface.
-
- Depths deeper than the deepest depth in the dive profile display now
- show a 'v' in the deepest depth rather than not being displayed at all.
-
- Bar graph now automatically reverts to a 2:1 scale in both loading and
- absolute display modes. For instance, if any compartment exceeds 100%
- loading, the graph will rescale to 0-200% (similarly for absolute
- pressure display).
-
- Autodecompression: When NDLs have been exceeded, the diver can
- autodecompress by entering 'd' at the depth prompt. This will cause the
- program to advance to the nearest 5' deeper than the indocated ceiling,
- and follow the ceiling up in 5' increments. This will produce a profile
- exactly equal to that used in calculating the 'time to surface' value.
-
- If available on your keyboard, the up and down arrow keys can now be
- used to change depth by one depth increment (as shown in the profile
- display) with each press during calculation. This is mainly useful while
- plotting a portion of a profile (i.e. 60' for 50 minutes), and you want
- to create a more realistic profile by moving up or down while
- calculating.
