Have it, do it, well something similar:
compile_opt defint32, strictarr, strictarrsubs
(the first two are the same as idl2). Still I would like it to be the
default for *all* functions. I mean, IDL2 came out how long ago?

Perhaps, but as long as my primary task is to produce printable output
as well, I don't feel the need to learn *two* graphing methods. Just
give me *one* that really works. WaveMetrics got it right with Igor
around 1990, so what is ittvis waiting for?
