There were a lot of conveniences in the old SAS/FSP product viewers FSView and FSEdit, including the command
which took the display to the named variable.
Without that in ViewTable, you're unlucky.
Try the hide/Unhide option on the ViewTable Data menu
It might help you to reduce the list of columns to something manageable.
In UNIX the FSView window supports the Move function which displays that column. This is one of the reasons I have rearranged the order of columns in a dataset. If they are alphabetical, they are easier to find.
