this help file uses UTF-8 encoding with the KAPL font
when using kedit from console do this first "export LC_ALL=UTF-8"

Note that APL\360 is one of the earliest APL's and as such is not the
easiest to use, especially when one tries to edit a function

APL\360 was typically used with IBM 2741, 2740 or 1050 which were all
Selectric typewriters using removable typeheads

APL\360 was run via hercules with OS/360-MVT 21.8F
and has a copyright date of 1972

⌹2        with some versions of apl the reciprocal is returned if the 
          right argument to matrix inverse is a number, but in apl\360
          this generates a rank error
