RSX11M FORTRAN installation (MTREK)

[C# Instruction]

Hello,

I'm trying to get MTREK to work based on the instructions in the PiDP-11 Manual. The MTREK command procedure is failing on the TKB commands because it can't find F77OTS.OLB.

FORTRAN appears to be installed, as the F77 command produces a "F77>" prompt. Other than the commands listed in the manual (which I see are a copy/paste of a post), I have not modified RSX11M as it was configured in the original installation.

Any advise is appreciated.
Thanks,

Kevin.

Are you interested in figuring out how to build it, or to run it?
Because it already exists as an RPM if you have that installed...

Otherwise you'll have to tell us how you are trying to build it before
anyone can tell what you are doing wrong.
But there isn't any "F77OTS.OLB" with F77. The libraries are either
F77FCS or F77RMS, depending on what file handling libraries you want to use.

I got MTREK running a couple of years ago on my PiDP RSX system and here are my notes.  See Step 7 that addresses the F77OTS.OLB issue:

Get the MTREK code
1.    cd /opt/PiDP11/systems/rsx11mplus
2.    wget http://rsx11m.com/PiDP11_DU1.zip
3.    unzip PiDP11_DU1.zip
4.    attach rq1 PiDP11_DU1.dsk

Install MTREK
1.    SET /DEF=DU1:[1,1]
2.    @MOUNT RSX83B
3.    DIR RSX83B:[*,*]MTREK.*
4.    UFD DU1:[307,110]
5.    PIP DU1:[307,110]=RSX83B:[307,110]*.*;*
6.    SET /DEF=DU1:[307,110]

7.    Edit (EDT) the .TKB files to change F77OTS.OLB to F77FCS.OLB

8.    Need to edit the TERMINAL.FTN file and add TTYPE and QUICKUP lines before compiling
>EDT TERMINAL.FTN
*’2150’
*C
2150  CONTINUE
      TTYPE = VT100
      QUIKUP=.TRUE.
      RETURN
      END

Start MTREK
@MTREK
@MTREKUP
SHP starts the game for a player
RUN ROBOT creates robot ships

Terminating the Game
Q

If the  universe   manager   MTREKD   does   not   terminate automatically (it does at CRC) abort it as follows:
<CNTRL> C
MCR> ABORT MTREKD

If you are running any ROBOT  programs  abort  each  one  as follows

CNTRL- C
MCR> ABORT ROBOT

[C# Instruction]

This looks great! Thanks. I started the process, but for some reason I can't get EDT or TECO to work the way I expect (and I screwed up the CMD file in the process). Once I get that ironed out, I'll follow your notes in detail.

Regards,

Kevin.

I believe EMACS is installed on the PiDP RSX-11 image, so you might try that for an easier to use editor. 

[C# Instruction]

I just want to run it, but am willing to build it if that's what it takes. 

I'm following the instructions from the PiDP manual, section 3 (https://obsolescence.dev/pidp11/PiDP-11_Manual.pdf).

I tried running the tsk file,

    RUN DU1:[330,16]MTREK

 but I got

   INS -- Common block not loaded LEDFOR

I tried chasing that down, but have not solved it yet.

Thanks though. I did make some progress.

[C# Instruction]

Thanks. For years in the 1980s people told me to dump EDT (which I was using because I was spending most of my time on VMS) and use EMACS. Looks like they have finally won :-)

[Johnny Billquist]

Ok. So you are trying to build it yourself.
Did you ever read README.1ST ?

FWIW, I never had any issues using EDT with PiDP11. Have you set up
your terminal type properly? "set term/inquire" in DCL is usually the
best way to approach it. Assuming you're using any DEC terminal or a
terminal emulator (PuTTY, xterm, TeraTerm or even Windows Terminal)
with a decent ANSI compatibility.

[C# Instruction]

No. I'll check that out. Thanks.

[C# Instruction]

Thanks. I'll give that a try. I'm using Terminal window on Linux Mint Cinnamon.

[C# Instruction]

With your help, I was able to get MTREK up and running. I learned a few things, and was reminded of stuff I knew a long time ago. I might make a video about it, as it was a good exercise.

Thanks,

Kevin.
