Fw: Syntax for vertical passages (and LRUD in general)

[Wookey]

A query from the therion list that is relevant to survex too. These
extra measurments are just a syntax for specifying cross-sectional
info on vertical passages. Does the survex *passage stuff support such
a notation (i.e. a way of specifying a vector for a measurment)?

I also noted in Austria this year that *passage does not support '~' for
'approximately', or multiple values eg. 2(8) for e.g. general passage
a canyon floor. I use these extensively in my notes and it would be
very nice if there was some way to include them in the data so the
computer could do something useful with them. 

Also ignoreall or ignore or 'description' does not seem to work in
*passage either, which is tiresome. This may just be a case of not
reading the detructions properly, but in fact it seems hat *data
passage is not actually documented yet (it is in v1.0.39 isn't it?).
That I can fix. 

If there is a consensus that this is useful I could have a go at
adding it - it's probably not hard.

Hello fellows,

I've faced a problem when I started to use therion for the surveys we do. The 
matter is that when we survey a vertical passage (a well) we are used to take 
such sets of measurements: shot from-to, length(vertical) and 3-5 
combinations of azimuth and distance. 
Ex. 1-2 5m. (210' - 1,2m)(0' - 4m)(75' - 3m)(160' - 0m)
210' stands for 210 degrees etc.

And I cannot  find out how using syntax of therion to note these measurements. 
Or should I change the way I do notes.

Thanks for any ideas and advises.
