In IDL, there's also a routine called READS, which works like READ or READF,
except that the input is a string instead of the keyboard or a file. Thus, one
could do things like

READS, '1.23 4.56 7.89', X, Y, Z

and can even use FORMAT statements. I don't know if this also exists in
PV-Wave or not.
