Add an argument to %Scan to calculate and return occurrences of the search-arg

Objective: To have an argument in %Scan that returns the total number of occurrences of the search argument in the search string.

for example...

string = 'hello world'
count of 'o' = 2

Below is a suggestive implementation using a hypothetical reserved word for indicating that only occurrences need to be counted (and not the position)

n = %SCAN(search argument : source string {: *OCCUR})
n = %SCAN('o': 'hello world' : *OCCUR) // and the output in n is stored as 2
n = %SCAN(*BLANK: 'hello world' : *OCCUR) // and the output in n is stored as 1

    I could use that as well (currently using a procedure I wrote myself).

    No idea about the implementation but a separate %ScanCnt procedure would be fine as well.
