LSE setting characteristics of initial buffer on entry

I knew this at one time, but my memory has faded away.

How do you set characteristics such as SET WRAP and SET TAB_INCREMENT on the buffer created when you invoke LSE with a filename (e.g., $ LSE SAMPLE.FOR)?

I've tried setting them in my LSE$INITIALIZATION file and while things like key definitions work, the SET WRAP, etc., silently disappear and if I remember correctly its because the buffer I want these set for is not the current buffer at the time the Init file is processed.

But I don't recall what the workaround is...

Any help?

It's been a long time since I used LSE and I don't remember exactly... but maybe this might ring a bell... do you go to the $DEFAULTS (or $DEFAULT I can't remember) buffer and make your changes there so that it will apply to future buffers?

Hope that helps a bit... or I could be totally off from what you're asking.

Thanks Edgar, that got me partially down the road - I had the sequence of events backward - the settings in LSE$INITIALIZATION are indeed being applied to $DEFAULTS and then inherited by any buffers created EXCEPT if the buffer is associated with a Language in which case the Language defaults for wrap, tab increment and right and left margins override those for the $DEFAULTS buffer.

Since I can't (and wouldn't want to) change the systemwide Language settings, I need to figure out another way to automatically change the wrap and tab increment settings for the buffer after the Language settings have been applied

Found it. Edgar, I wish I could drop a couple of more points your way as you sent me down the right path.

Here's how its done (using LSE syntax, not PLSE):

$LSE
LSE> MODIFY LANGUAGE FORTRAN /WRAP /TAB=2
LSE> SAVE ENVIRONMENT
LSE> EXIT
$ DEFINE /NoLOG LSE$ENVIRONMENT ! in LOGIN.COM

and voila, buffers created either implicitly or explicitly with language FORTRAN will get those attributes.
