and evaluates as true if all the conditions in the and statement are true. The ampersand symbol ‘&‘ can be used as an abbreviation.
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
HDL is high and Trig is normal
HDL is high & Trig is normal
all HDL are High and all Notes values ends with “note”
HDL > 6.0 & LDL is “pending” & Trig > 3.5
Note that more than one & may be used in a condition. However, it is recommended to use several shorter conditions, rather than a long and complex condition involving multiple & keywords.
The last example condition could therefore be better expressed as three shorter conditions:
HDL > 6.0
LDL is “pending”
Trig > 3.5
