Subroutine names

The CAT subroutine names follow the normal Starlink format of a prefix, an underscore (`_') and a five-character routine name (see SGP/16[9]).

For most routines, the first letter of the main body of the subroutine name denotes the sort of item that the subroutine operates on, according to the following scheme:

T	-	total, or whole catalogue,
P	-	part (column or parameter),
C	-	columns (entire columns),
R	-	rows,
Q	-	parameters,
E	-	expressions (algebraic expressions),
S	-	selections,

The ADAM routines (see Section ) are exceptions; they have names chosen to be consistent with the corresponding routines in other ADAM libraries.
