Showing the "use back command" tip only makes sense when doing interactive debugging

[Dylan-Brotherston]

$ mipsy /tmp/t.s
error: could not find instruction at 0x00400228

tip: try using the `back` command - the instruction that brought you here was:
0x00400220 30  [0x16f00002]    bne    $s7, $s0, crash   #  bne $s7, $s0, crash

I think the tip is still pretty useful but it should specify to perform these actions in the mipsy cli, maybe even list out the specific instructions required to run the program in the cli and get to this point?

looks like the uninit instruction error isn't checking error context properly...
