I must use
IF ((type(k) ≠ 6) OR (type(p) ≠ 6)) THEN
instead?

The "type" command is different from the "TYPE" command (see their respective help screens in the Toolbox Catalog). Both work correctly in CAS, but Home's parser interprets "type" as "TYPE", which causes the following unexpectedly different results:

CAS: TYPE( {1,2,3} ) --> 6
CAS: Type( {1,2,3} ) --> 6
CAS: type( {1,2,3} ) --> DOM_LIST
CAS: type( {1,2,3} )+0 --> 7

Home: TYPE( {1,2,3} ) --> 6
Home: Type( {1,2,3} ) --> 6
Home: type( {1,2,3} ) --> 6
Home: type( {1,2,3} )+0 --> 6
