/tmp/testit.m4:
define(`First', index($1,`@'))
First(address@hidden@baz')
index(address@hidden@baz',`@')
address@hidden:/tmp$ m4 testit.m4
-1
3
address@hidden:/tmp$
I'm stumped as to why the index call in First returns -1, whereas the
direct call returns the correct index. In trying to understand this,
I've defined a 'myindex' macro that simply returns its arguments, and
they are the same in both cases.
Any help would be appreciated.
