Whoops, its just reading from a file, I messed with it earlier and
forgot to change it back, It should be:
PRO inputer
print, 'starting input'
getfile = DIALOG_PICKFILE (/READ)
print, getfile
OPENR, 1, getfile
POINT_LUN, 1, 0
IDL_Name = ' ' ; want extendable length if possible.
READU, 1, IDL_Name
print, IDL_Name
POINT_LUN, 1, 0
CLOSE, 1
END
Ideally,
This idl file just reads whatever file is selected and stores the name
variable to IDL_Name .
But what I want to do is 'search' the file opened for certain words,
when it finds them I want to be able to store that value to an IDL
variable.
Im going to need to declare more variables then IDL_Name, but im
unsure how to do it.
ie: if the user selects this file:
Name = {Joe}
Department = {CS}
Age = {25}
I want in IDL to have those 3 variables stored ie:
IDL_Name = Joe
IDL_DEPARTMENT = CS
IDL_AGE = 25
But, if the file reads:
Age = {30}
Department = {Science}
I would want IDL to return;
IDL_DEPARTMENT = Science
IDL_Age = 30
I think i need to use some sort of 'search file' command. I hope this
is clearer, sorry for being unclear before.
Thank you! and David your website has been of help to me frequently in
the past.
