The IDL documentation contains several READ... routines supporting
various file formats. Basically you can read ASCII and binary data,
and there are routines to handle in/and output of net-CDF, CDF and HDF
format (I am not familiar with those personally though). Also, there are
several image formats that can be handled,e.g. GIF, JPEG, TIFF.
If you just start using IDL you may have some difficulties reading data
(I guess that happens to everyone). If you are dealing with ASCII files
you can try my readdata.pro program which you can download from the
webpage below. This allows you to skip arbitrary amounts of header lines
and recognize variable names if you tell it where to find them. However,
it only deals with numerical data - mixed type stuff is somewhat
trickier, but (as David pointed out): it can be done.
Regards,
Martin.
