    Phil -

    I believe this takes someone old enough to have learned programming
first in FORTRAN....

    For formatted reads, you basically want to include only variable
descriptors and spaces (nX), so the colon and "," are counterproductive.

    Have you tried something of the form:

IDL> READF, lun, variable, FORMAT = '$(n(f6.6, 2x))

    That is, you just want to skip the commas and read the floating-point
variables.

    Hope this is what you're looking for.
