I'm seeing this in both the release and this morning's CVS versions. A test
file that illustrates the issue:
mac-lkollar:/tmp lkollar$ cat -n test.t
1 .nr NCS 1
2 .nr SIP 1
3 .LP
4 This is a test,
5 .if \n[NCS]&!\n[SIP] .nop NCS only.
6 .if !\n[NCS]&\n[SIP] .nop SIP only.
7 .if \n[NCS]&\n[SIP] .nop NCS and SIP.
8 .if !\n[NCS]&!\n[SIP] .nop actually it isn't because nothing is defined!
mac-lkollar:/tmp lkollar$
Running groff on this file produces the warnings:
test.t:5: warning: numeric expression expected (got `!')
test.t:8: warning: numeric expression expected (got `!')
Using parentheses doesn't change the results at all. Can anyone suggest a fix
or at least a workaround?
Thanks,
