ASUM()
Short:
------
ASUM() Determines the sum of an array with condition
Returns:
--------
<nArraySum> => Array sum
Syntax:
-------
ASUM(aTarget,[bCondition])
Description:
------------
<aTarget> is the target array. Normally an array of
numeric values. [bCondition] is an optional codeblock used to
select a subset of the array. This could be used to filter out
0's or non-numeric elements.
The block must accept an array element as a
parameter, and return true or false <expL> to determine if this
element is part of the desired subset.
Examples:
---------
v := ASUM(aSales)
v := ASUM(aSales,{|e|valtype(e)=="N".and.e<>0})
