RSX-11 trouble

Looks as if the @ task, the indirect command processor, is either defective, or was not linked correctly for this system. Check the system generation manual; there are hints on how to replace it. This is for instance necessary for a sysgen (INS a /BIG version of it). If this fails, the TSK is broken. The sysgen rebuilds IND from an OLB regularly; there is a BLD file for this. You don't need to run a full sysgen for it (infact, with a broken @ processor, you can't).

Subject: RSX-11 trouble

Got a MicroPDP 11 plus.
It seems to be misconfigured.
It can't execute .CMD files, reporting
Task "...AT." terminated
Load failure. Read error

No disk errors are reported with ELI DU0:/SH

Disk seems to work: I can run .TSK files.
The file STARTUP.CMD isn't read at all.

Any hints? Which file is executed right before STARTUP.CMD?
I see two RED commands and a MOU before it tries to read [1,2]STARTUP.CMD and reports the aforementioned error.
