I thought I understand array subscripting in PV-wave but this bit of
code has got me foxed. I was trying to figure out what was going wrong
with a procedure and finally tracked it down to a problem that I can
demonstrate using the following example:
WAVE> a=indgen(3)
WAVE> print,a
0 1 2
WAVE> m=[45,99]
WAVE> print,m
45 99
WAVE> a(m)=255
WAVE> print,a
0 1 255
Now, I would have thought that because both elements of 'm' are more
than the size of 'a', no element of 'a' would have been assigned?
The values '45' and '99' are completely arbitrary. You can set them to
anything you like.
If someone could explain what's going on here (maybe it's a bug??) I'd
be most grateful. The configuration is PV-wave 4.01 running on SunOS
4.1.3.
Thanks.
