good job, Lajos! It does run as fast as idl6.2 with some of my old
code. i've noticed backingstore problems with my linux machine. device,
retain=2 does not work. i'd like to know how to set working dir/search
path/start_up file.
cheers,
bp

Thanks!
HELP, /LIB will list all system routines with available parameters.
RETAIN for DEVICE is not allowed yet, but it is on my todo list.
time_test needs write permission to the current directory. You can move
around with CD, 'dir' (read the working dir with CD, CURR=curr & PRINT,
curr). Search path is the normal !PATH. The start up file name can be
given in the FL_STARTUP env. variable.
So you can run time_test by
CD, 'some_dir_with_write_permission'
!PATH+=':/usr/local/rsi/idl/lib'
TIME_TEST3
regards,
lajos
