Fixing Dungeon on RSX 4.2

So I'm working on fixing some old code here. Found my balticon gaming system disks from 1990 (yes, I used to drag a pdp11 and 4 terminals to Balticon and other cons for computer gaming) and dungeon works on the 4.0 RSX version I was using but when I try to run it on 4.2 I get an Error 4 at PC 162570. I tried recompiling: RSXCMP works fine and compiles all the modules however when I run TKB with the rsxbld I get a bunch of *DIAG* Segment (root3, rooms, etc) has address overflow: allocation deleted. What am I doing wrong today? The task builder file is: dungeon/cp/fp=d.odl/mp stack=384 libr=fcsres:ro asg=sy:1:2:3:4,TI:5,CO:6 Reading the docs I see: The Fortran-IV-Plus object time library must be merged into the system library (SYSLIB.OLB). Further, the library must be set up to invoke the short error text module ($SHORT) as the default. Task building with a separate object time library produces numerous errors; task building with a resident library or the normal error text module produces an oversize task image. This might be the problem, anyone remember how to put the short error text module into syslib.olb? Hm. Maybe it is. Hm.... C
