Missing files in <MDLLIB>

[ZoBoRf]

https://github.com/PDP-10/muddle/blob/master/%3Cmdl.comp%3E/pdmp.save.6 references DSK:<MDLLIB>SORTX.NBIN, which is missing among others.

On TOPS-20 we can say:

mdl105
MUDDLE 105 IN OPERATION.
LISTENING-AT-LEVEL 1 PROCESS 1
<SET V [1 MONEY 2 SHOW 3 READY 4 GO]>$
[1 MONEY 2 SHOW 3 READY 4 GO]

<SORT <> .V 2 1>$
[4 GO 1 MONEY 3 READY 2 SHOW]

SORT calls the SUBR SORTX which I am trying to find the source code for, because

On ITS SORTX is currently missing:

:muddle
MUDDLE 56 IN OPERATION.
LISTENING-AT-LEVEL 1 PROCESS 1
<SET V [1 MONEY 2 SHOW 3 READY 4 GO]>
<SORT <> .V 2 1>$
[1 MONEY 2 SHOW 3 READY 4 GO]

*ERROR*
UNASSIGNED-VARIABLE
SORTX
GVAL
LISTENING-AT-LEVEL 2 PROCESS 1

Thanks for testing ITS Muddle, this is something we need more of. We haven't found any ITS directory corresponding to MDLLIB, so for now everything is missing. The plan for the future is to try to port TOPS-20 MDLLIB back to ITS.
