I am surprised that Mort Canty replied to my question. Yes, the
program is the first example in your book! And Dr. Fanning, I am
reading your book too!

Problem not solved.
I put all the files (pro and ENVI data) on the IDL path, and added two
lines:

COMPILE_OPT idl2
FORWARD_FUNCTION envi_select, ENVI_GET_DATA,envi_file_query

The 'ENVI_GET_DATA' turned into different color, I guess IDL knows
about it, but I got an error message:
Attempt to call undefined procedure/function: 'ENVI_SELECT'.
Actually when I tried to remove the for statement, I got the same
message as above. If I removed the envi-select, then envi_file_query
is the problem.

Fanning, thanks for pointing out the IDL path. I found IDL sometimes
only runs the old file for me, that is the reason.
Mort, I did not forget the '$', I wrote the statement into one line.
And 'fhame=fname ' won't work either.

Thanks a lot for your time to help a newbie ^_^
