Additions how MTREK was found and debugged

	While searching the Internet for information on the [[VAX]] [[TREK7]] game, I stumbled over another Star-Trek game called "MULTI-TREK" or just '''MTREK''' in the [[DECUS]] [https://www.digiater.nl/openvms/decus/ collection of VMS software tapes].		While searching the Internet for information on the [[VAX]] [[TREK7]] game, I stumbled over another Star-Trek game called '''MULTI-TREK''' or just '''MTREK''' in the [[DECUS]] [https://www.digiater.nl/openvms/decus/ collection of VMS software tapes].

			I used the [[ods2]] tool from the [[SIMH]] [https://github.com/open-simh/simtools tools collection] to transfer the MTREK files to a VMS disk image file.

			I decided to use the [[FORTRAN]] source files instead of the [[RATFIV]] ones, because I could not get the RATFIV [[compiler]] going (I will try that again later).

			The date of the RATFIV source files (28-APR-1982) gave me a clue to try [[VMS]] V3 for MTREK, which proved to be successful.

			Using the @BUILD command gave some error messages, which were overcome in some steps by trial and error.

			The nasty surprise showed up when I started the MTREK program that had compiled and linked so easy.
			Directly after entering the chosen vessel number, the program "froze" and did not accept anymore input except CTRL-C or CTRL-Y, both of which aborted the game.
			After studying the sources, and some simple debugging attempts, I decided to employ the VAX [[debugger]] to obtain more information as to what was going on.

			A helpful chap from the U.K., Dave Roberts, replied to my call for help on the [https://forum.vcfed.org/index.php?forums/dec/ VCFed DEC Forum]; and together we attempted to debug and correct the errant behaviour.

			The first step to success was the detection of the endless loop that caused the "freezing" of the program.
			Then Dave found the suspicious subroutine "INCHAR", and after analyzing the QIO calls and their return codes with two VMS manuals I provided, he finally found out that a necessary initialisation routine was commented out for whatever reason. After removing the "C" (for "Comment") in the respective source line, followed by re-compiling and re-linking, MTREK ran as expected. Little cause for a great event ...

			Hurray, game time!

			This is an example of a player's view at the universe:

			Energy : 9848.5 * * Scores
			Shields : 0.0
			R 1 -1000. *
			Warp : 3.00 * 2 0.
			Course : 3.00 3 0.
			4 0.
			X co-ord : 38.8 * 5 0.
			Y co-ord : 89.5 1 6 0.
			# 7 0.
			Torps : 10 8 0.
			Seekers : 4
			Hyper : 3
			Scan: 2
			Def Ship : 2 * Dir : 1.75
			Def Direc: 1.75 Dist: 51.08
			* Sect: 7, 2

			5.0 ADDITIONS TO THE MANUAL


			5.1 ADDITIONS TO STARTING THE GAME

			There are two special values for the startup settings which make
			playing easier for the beginner:

			1. Setting star density to 0 results in no stars in your way at all.

			2. Setting black hole speed to 0 will create no black holes to eat up
			your vessel.
