Hello all,
I have come across a very strage situation in which
the behaviour of groff seems to depend on:
a. whether it happens in a diversion or not and
b. the presence of a comment.
In the example below it is demonstrated using the
.tm request:
----------------------------------------------------
.de QS
. nr oldVPos \\n[.d]
. if (2=2) \{\ \"Remove this comment including the space in col. 17
' nf
. \}
. nr ofs (u;\\n[oldVPos]-\\n[.d])
. ie (\\n[ofs]=0) .tm \\n+[tn]. Test passed.
. el .tm \\n+[tn]. Test not passed: Offset = \\n[ofs]
. di quot
..
.
.nr tn 0 1
.QS
.QS
.QS
.di
.di
.di
----------------------------------------------------
With the comment in line 4, I get the following
error output:
1. Test not passed: Offset = -1
2. Test not passed: Offset = -40
3. Test not passed: Offset = -40
and, removing the comment so that the line 4 termi-
nates in '\', because even an empty space triggers
the problem:
1. Test passed.
2. Test passed.
3. Test passed.
Why is this happening?
Thanks in advance,
Anton
