Subject: Fix TVLOC overflow check.
X-Git-Url: https://jxself.org/git/?a=commitdiff_plain;ds=sidebyside;h=0f32b19f7b9d9c94fa87fae045a7e2cb270dee97;p=pdp10-muddle.git

Fix TVLOC overflow check.

The .LOP .VALUE here is a link-time assert (.LOP runs an arbitrary
instruction). But the test is the wrong way round -- at the moment,
TVBASE=44000, TVLNT=6000, TVLOC=47560, so overflow hasn't occurred.

The 1973 version of the code uses .LIFL, which makes more sense to me...
