hello,

a unexpected thing happens when a logical file unit is allocated in
the setup batch procedure execeuted when idl session is started. the
first use of get_lun at the IDL prompt returns the unit already in
use.


; LUN 100 is in use...

IDL> help,/files
Unit Attributes Name
100 Read, Write, New /tmp/idl-8391185

; but get_lun returns unit 100?

IDL> get_lun,fu
IDL> print,fu
100


this is not 'right'.

george
