Information needed (bad!)

[vsaariokari at abo.fi]

I'd like to get some information about statistical and SPC (Statistical
process control)- programs for ULTRIX. Also programs written in C-language
are suitable. I have studied SAS-system and RS- system programs, but
I'm searching also for smaller programs. Does some have experience
in using these programs ?

Is there any books including programs written in C-language for technical
use? ( One that includes FORTRAN- code exists! )

What kind of graphical programs exist for GKS and GKS-3D ? I mean prog-
rams that work in upper level of GKS, so that you don't have to use GKS-
orders, but can say for example "draw a line". 
I have studied SL-GMS. Has anyone experience in that program?
What other programs exist for ULTRIX ? 
What kind of program is PV-WAVE ?


I would be grateful if someone could answer some of my questions. Thank's 
already in advance!
