November 2023 update

**NOVEMBER 2023 UPDATE **

• I've corrected a bug with the Distance/Direction calculator within "com". Thank you Fern. Applies to PET, C64 & Plus/4 ports

**JUNE 2023 UPDATE **

• I've removed the PET & Plus/4 conversions from this page and I will be moving them to their own dedicated pages

** MAY 2023 UPDATE **

• Removed redundant code from my abandoned “full screen short range scanner” facility
• Fixed error trapping for direction/distance calculator within COM 
• Added correct message if “GAL” secret command is used and ship’s computer is down rather than going directly back to command input prompt
• Re-instated colours to title page now that I’m implementing colours completely differently

• Unified source code to suit PET, C64 and Plus/4 computers! It is just line 80 that tells the program how colour codes are implemented (if any) according the computer it's running on. This makes maintaining my releases MUCH easier. See download/install instructions after "plain text" file.
• Re-engineered the "SRS+Summary Data" display routine. Now MUCH MUCH faster in operation 
• Renumbered line numbers for program source code. No mean feat for Commodore machines
• Nice new feature: Added a command, "SLS", which displays both Short and Long Range Scans in one go

• Improved Galaxy Record display for VIC-20 with a new position highlight method (moved to separate project page)
• Corrected a minor formatting issue with "Starbase Protects Enterprise" message
• Corrected distance result in Enterprise-to-Klingons torpedo data report (even tho only the direction is actually useful here)
• Removed colour schemes for C64 version - too cumbersome to maintain eleventy-eight flavours
• Added Commodore VIC-20 version (moved to separate project page)
• Added Commodore Plus/4 version
• Corrected random seed generator for those systems that auto-boot into the game at switch on, like "Kung Fu Flash" etc
• Reduced battle reports (in both directions) from 3 lines per attack to 2 lines per attack
• Added "Max Warp" to SRS summary data display, which is based on condition of warp engines and available energy
• Reduced "Captain's Rating" to an integer
• Decluttered "title screen", credits are in the REMs of the program source code
• Added "Days Left" to SRS summary data display
• Added location of Enterprise highlight to LRS and galaxy record display
• Added a "secret" command; "GAL" which macros straight into galaxy record display, as long as onboard ships computer is not damaged
• Corrected the X/Y - Y/X inversion error with "Direction/Distance Calculator" within COM
• Significant restructuring of many routines
• Further reduction in unnecessary carriage returns making the game visually much more compact
• Corrected the logic behind when "press return to continue" prompt would appear for long post-battle reports etc

** APRIL 2023 UPDATE **

• Removed all double carriage returns for a more compact experience
• Fixed Starbase direction/distance calculator (was previously mathematically incorrect)
• Now with 80 column style SRS and Summary Stats!
• Added a new full-screen Short Range Scanner (command "SRS2") - now removed, causing slow down with normal SRS
• Tweaked all charts
• Further tidying up of non-chart outputs
• All colours now configurable (see program lines 73-88) - now removed

** MARCH 2023 UPDATE **

• Added disc image for CBM PET (40 column ONLY)
• Added a Long Range Scanner helper display
• Added LRS colours to Galaxy Record screen
• Added an SRS icons "key" to title screen
• Tidy up of Phasers dialogues, energy and damage displays
• Added an 8x dot progress bar to show galaxy creation on startup
• Limited numerous data displays to 3 decimal places
• Added a random seed generator based on internal timer
• Reworked the Damage Control reporting with conditional colour text - no longer numerics only
• Added "KEY" command to display key to SRS icons
• Indented many data outputs (ongoing)
• Added command list and SRS icon list to startup
• Adjusted decimals (x3) input with targeting and navigation (now matches targeting and navigation data outputs)
• Broken up post-navigation report into two parts to help with reading of damage data etc.

** SEP 2022 UPDATE ** 

• I've corrected various typos that were present in the original 1970s source code
• Enabled decimal point entries to Warp value
• Corrected small bug in NAV numerics (for decimals)
• Added a helpful direction display (thank you Les Orchard) for NAVigation entry
• Fixed (hopefully) various "divide by zero" errors... Thank you "ibitato".
• Reworked Photon Torpedo routines and also added Les' NAV helper 
• Fixed formatting issues with "Photon Torpedo Data" within COM

** AUG 2022 UPDATE ** 

• Replaced the C64's standard "input" command with my own "limited input" implementation  
• Corrected a few bugs; notably NAVigation entry

** JAN+ 2022 UPDATE ** 

• Huge re-formatting job of converting 80 column output to suit 40 column displays   
• Separated SRS chart from summary data from inline 80 column to two sections of 40 columns
• Added some sympathetically applied colours to key elements of the display
• Improved "grids" to SRS and LRS outputs, now easier to read with vertical divisions
• Re-engineered the Galaxy Map chart to still display in two main centred columns of 40 column output
