Hi,
I am sure this question has come up before, but can anyone advise an OS/8
change I can run to avoid the following issue (below)? I am unsure if I
need to fix my simh INI file or make more space for the program from the
OS/8 dot prompt, or FORTRAN * prompt.
Running pidp-8i (simh PDP 8i kit)
I load OS/8 and initiate the command from the dot prompt:
. FRTS
..dumps me to the * prompt ...
*RKB0:ADVENT.LD [return]
* [esc]
rather than loading ADVENTURE I get the following result:
D.F. TOO BIG INIT 0000
MAIN 1740
.
(..andkicks me back to the dot prompt).
the INI is the default
reset
set cpu 32k
set cpu noidle
att rk0 ../imagefiles/os8/advent.rk05
boot rk0
what changes are needed? I searched around, I don't quite understand how
to load an LD file in OS/8 to debug the error. It may be I have the wrong
RK05 disk, but I'd really like to understand what this error means if
anyone knows. My physical RK05 disk loads ADVENT as an SV file, I don't
need the extra steps.
Thanks
BIll

That stands for "data field too big", i.e., too much data to fit in 4KW.
That's as opposed to "instruction field", which if too big would mean that
there's too much code.
Although I used OS/8 Fortran in the distant past, I never tried to compile
large Fortran programs or programs that used much data, so I don't know
what it takes to solve that problem. Maybe there is some way to get Fortran
to use more than one 4KW field for data, issuing the necessary CDF
instructions to switch data fields?

Checking the OS/8 Language Reference Manual reveals that I was totally
incorrect.
That stands for Data File too big.
"Product fo number of record times number of blocks per record exceeds
number of blocks in file."
So I have no idea how to fix that.

Thank you. As said recently I have the SV file making this perhaps moot,

You need to specify the datafiles to use.
.R FRTS
*RKB0:ADVENT.LD
*RKB0:ADVENT.TX/1
*RKB0:ADVENT.DA/2
*$
.

For the record, that's a really ancient version of OS/8 Adventure.
The current (2009) is much more stable as it uses the USR to open the
files, allowing you to move them around without causing ADVENT to crash
(the save image has the disk locations for the files being used, meaning
it'll crash if they move around.)
https://www.rickmurphy.net/advent/advbin.rx has a floppy image with 2.4
binaries.
