Gempak - IRIX64 - SNPROF : theta-e lines, labels

Institution: Universite du Quebec a Montreal / Atmospheric Science Group
Package Version: 5.6.K
Operating System: IRIX64
Hardware Information: SGI
Inquiry: Hi,

I have two issues in using snprof.

1- theta-e lines
These pseudo-adiabats are specified in fixed increments, but the problem is 
that they do not coïncide with the intersection of 1000 hPa line and 
temperature lines, as it would be in this example skew-T :

How would it be possible to do that? I tried to look into the source code, but 
saw no obvious way to do it yet. I am still looking in the possibility of 
source code modifications for default behavior change.

2- Labels of theta-e and mixing ratio
They are not labelled, this issue has come in the support of GEMPAK earlier, no 
solution yet. I did look into the code too, but found that it is even more 
difficult for me to figure out how to draw labels...

In both case, would it be possible to get some tips on what to look for and 
which subroutines I could use, especially for issue #2?

Thanks!
