Here's a question for anyone who reads unformatted strings.
Is there a way to read a whole ,say 10 character, string at once
in IDL? Here's what is happening to me.
1)Open an unformatted idl file and write a silly string like 'stumblefloppy'
get_lun,unit
openw, unit, 'silly.dat'
writeu,unit,'stumblefloppy'
free_lun, unit
2) Try to read the string
bonk=' ' ; this is the string variable that I read into
get_lun,unit
openr, unit, 'silly.dat'
readu, unit, bonk
3) OK, I'm ready to print 'stumblefloppy'!
print,bonk
s
's' !?!? Just the first character. If I define bonk to be two spaces or three
spaces then i get 'st' or 'stu' back. I know it's cause each character is 2
bytes or something like that. Is there any way, other than defining bonk as 13
blank spaces before reading,
that I can read this string? Any bright ideas would be appreciated!

The external data representation is just the thing
