Snap and Globe data is identified by either the channel name or the channel number. If you use the channel name, you must set the digraph to ``S'' for Snap or ``G'' for Globe (DI S or DI G). Globe channels are 1-199; Snap channels 1000-1999 are vectors as a function of the major radius; 2000-2999 as a function of the minor radius.
Snap output is identified by both a shot number and a ``try'' number. The default try number is the highest; to override this, append the try number to the shot number with an underscore:
SH 55806 !default try number
DE [S]POH ; !integrated ohmic power
DE 2204 ; !same data by channel number
SH 55806_2 !use try number 2
DE POH ;
