defs problem

[David Middleton]

Despite having used lout for some time I've only just started
trying to make use of the "mydefs" file to keep some useful
definitions together.  It's causing me some trouble.

Consider the following two examples:

i)  A lout file:

@SysInclude {doc}
@Doc @Text @Begin

@Display {test}

@Display {test}

@End @Text


The output in this case (from lout -p, same effect with ps output) is:

                                      test


                                      test


ii) A mydefs file:

import @DocumentLayout
def @Title right x { @Display x }

and a lout file:

@SysInclude {doc}
@Doc @Text @Begin

@Title {test}

@Title {test}

@End @Text


In this case I get the following output

         test                           test


Why the difference?


Another query:  when I put multiple definitions in the same file
why is it necessary to put an "import @DocumentLayout" line before each.
For example, lout complains about

import @DocumentLayout
def @Title right x { @Display x }
def @SubTitle right x { @Display x }

but accepts

import @DocumentLayout
def @Title right x { @Display x }
import @DocumentLayout
def @SubTitle right x { @Display x }


Thanks in advance for any insight.  I'm using Basser Lout v3.10 on
Solaris 2.5.
