If the machine has memory address and memory contents registers, then 
ASSERT can be used to verify memory values.  I am  not familiar with the 
PDP-11, but for the HP 2100 simulator, the M (memory address) and T (memory 
contents) registers can be used as in this example:

  deposit M 126
  assert T=13

This would verify that location 126 contained the value 13.  Perhaps the 
PDP-11 has similar registers?

Yes, that is precisely why the ASSERT command was developed.
