I got my project-a-line-into-a-plane PP program working, and it's fast. I also wrote some code to interpolate the resultant image (a collection of lines) into something resembling an image - as far as I could tell, none of the available interpolation functions did what I needed. So, if anyone wants to know how to turn a bunch of images taken at different angles into a data cube (HI position-velocity maps are the only application I've thought up), I may have the answer.
Jarle and Doug, thanks for your help. I wasn't able to get the inline pp running, but I got the makefile version to work, and while debugging it was a bit painful, the final code is very fast and does what I need. Minor sidenote: I have a recommended change to PP.pm. I was consistently getting the error: Access Index not found: c, 0, n and couldn't figure out what it meant, so I went into the PP.pm code and started printing out everything I could find, and I found that "$incname" and "$substname" (around line 452) were the labels I was supposed to be using. It would be nice if the "Access Index not found" error printed that out as well - e.g. something like Access Index not found: c, 0, n (expected n0) The documentation actually does say that you need to use e.g. n, n0, n1.... if you have square PDLs, but it wasn't that clear what to do when my signature was (a(n),[o]c(n,n)) - apparently, for any references in the 1-d pdl, you just use "n", but in the 2-d piddle, you use "n0" and "n1".
