OK, I am thinking if your old box has TCP/IP then it is NOT M36 but
it is OS/400 with the S/36 environment installed. Even the first
AS/400's didn't have TCP/IP. Can the box do any os/400 commands at
all? Well, duh, Rob, of course it does. If he can save it to save
files it must be S/36 environment and not M36.

TCP/IP has been around since long before the OS/400 V4R3 that the OP notes is installed, running a *M36. The above quoted reply seems to muddle the difference between the actual system models that were effectively the S/36 running on a RISC system and the *M36. The system model was almost indistinguishable from an AS/400 IIRC, and was called the "Advanced 36". The Machine-36 hosted partitions\systems were running instead, on a RISC AS/400 with OS/400; there could be multiple *M36 objects on one AS/400. A system running its S/36 applications running in a "machine 36" object [see CRTM36 CL command] need not ever have installed the S/36E feature to do that, because the applications could all be running in those hosted "machines".

The first two lines of Jim Franz's reply earlier in the thread suggests that the *M36 is "like the Advanced 36-236 or 436", but that it is "hosted on a OS400"; albeit the text was rearranged from how I quoted it here, so that may be confusing to those who are not aware of both as being distinct entities:
"M36 is a true look a like of a System 36, hosted on a OS400 - like the Advanced 36-236 or 436

I believe the *M36 also implemented virtual communication between that system partition to the OS/400 so data could be sent betwixt; and for all I know, there may have even been a FTP client made available to the Advanced 36 and thus to the *M36 which was effectively that OS [SSP on RISC].

Anyhow the old TCP/IP for OS/400 was written in PASCAL, but it did exist, as the following IBM i 7.1 doc suggests the TCP/IP utilities were available since before v3r1m0:
Convert TCP/IP CL Source (CVTTCPCL)
"The Convert TCP/IP CL Source (CVTTCPCL) command is used to convert TCP/IP commands from releases prior to Version 3 Release 1 Modification 0 (V3R1M0) to the command syntax for the current release. The pre-V3R1M0 TCP/IP CL commands to be converted must exist in a source physical file.
