all evaluates as true if a statement is true for all episodes in a sample sequence. ‘Each’ is a synonym for ‘all’ that may be used to create more natural sounding conditions.

For example, given the following case fragment,

                      05 Feb 03    06 Oct 03    07 Nov 03
HDL      [2, 5.5]        7.3*         5.6*         6.1*
LDL                      1.1          0.8          pending
Trig                     3.2                       3.6
Notes                 1st note     2nd note     3rd note

all HDL are high
all LDL are available
each of latest 3 Notes values ends with “note”
