REROAM
Type:  Verb
Use:   To reenter the roam operation using the roam modes set up by a
       preceding TVROAM.  See HELP ROAM for a description.
Adverbs:  none

Use ROAMOFF to capture the resultant display in a simple TV display on
which the other TV verbs may function normally.

Note that TVTRANSF with TVCHAN=0 will act on all channels that are
used for the roam when the TV is in roam mode.  Thus you can do a
TVROAM, adjusting the screen to select the desired subimage, then hit
button D.  Set TVCHAN to zero and do a TVTRANSF to set the best
transfer function.  Then REROAM to examine the image with the desired
scaling.  But, as of 28-May-2011, you may also do this enhancement
while running TVROAM or REROAM.
