Set bit 5 in FLAGS to 1.
The input unit table structure is shown below.

with other functions that require a unit name as input. If you know
the look-up value corresponding to the unit name, you can substitute
it for the unit name in the input unit table. The following figure
represents the first two fullwords of the unit table when function
code 5 is requested.
