Help! How to get the weather information of a point plot?

[z z]

Dear Lee
Thanks for your reply. But I still have a question about the fwrite.
For example:
I want to collect the paramters value of the point(-90 45)) and write
these paramters to a binary file. I wrote the script like this:

'set lon -90 -90'
'set lat 45 45'
'set t 1'
'set gxout fwrite'
'set fwrite output.dat'
'd z'
'd u'
'disable fwrite'

The output.dat file was generated. But how can i open and read this
file from another application? is it a standard binary file? I got
this unreadable info "C p·?㘠" when I try to open this file in an
text editor.
Is my understand right? expecting your response
Thanks alot
