This is not a simple one. If you call Get_SysInfo(), it sends the following @fm-delimited information to the client using Send_Dyn:
<code>
equ DBID$	to 1
equ USERNAME$	to 2
equ ADMIN$	to 3
equ SERIAL$	to 4
equ VERSION$	to 5
equ CPU_TYPE$	to 6
equ COPROC$     to 7
equ MEM_AVAIL$	to 8
equ DES_AVAIL$  to 9
equ NETWORK$	to 10
equ STATION$	to 11
equ MAX_USERS$  to 12
</code>

So you have to shell Send_Dyn. (A planned feature is to support a BASIC+ callback from Send_Dyn so this would not be necessary.)

Alternatively, here is the binary for SYSOBJ/$MAXUSERS, a function which returns the maximum number of users:
00010001001300120000008A18E31429

This sounds great, but can you give me an example of shelling Send_Dyn? I have not been able to get this to work. Also, if there is already a function (SYSOBJ/$MAXUSERS), can't I just make a Maxusers call and accomplish the same thing?

Cam has created the maxusers function for you. You need to grab the hex and write it as binary to $MAXUSERS in Sysobj.

If you already have a SYSOBJ/$MAXUSERS then it probably returns the maximum number of users. I have such a function, but I did not think that it was shipped in the product. To test, in the System Editor command line execute the following:
run maxusers
The reason I posted the binary for the function SYSOBJ/$MAXUSERS it that there is a maxusers() function available but it is intrinsic (implemented by the compiler, not by object code in the SYSOBJ table) and furthermore it is accessible only from the system compiler.
