May I suggest the help files - things have changed. There is a new
adverb TV2CHAN (and GR2CHAN) which can be added to your vocabulary with
COMPRESS. The 2 channels of a blink are now set with TVCHAN and TV2CHAN
and there is actually a channel 12 (up to 16).
It appears that there is a bug in handling the adverbs which I should
fix. Sigh.... I am buried in a very useful but mentally challenging
attempt to make aips run faster.
