B.4.7 recall

With no arguments, recall prints the last 20 commands given, numbered with 1 the oldest. With a numerical argument, it re-runs that command from the command list. The only tricky part of this is that as new commands are entered the numbering shifts, so the same number can refer to different commands later in the session.

On Unix systems, this is rarely necessary, since the up and down cursor keys serve the same function and allow the recalled command to be edited.

Example:

xsel:ASCA-sis1 > recall

   1: set inst sis1
   2: choose 1-2
   3: faint
   4: bin image
   5: save image my_image.fits
   6: show status

xsel:ASCA-sis1 > recall 2
 choose 1-2
