COUNT(), COUNTS() |
![]() ![]() ![]() |
The COUNT() function counts occurrences of a substring within a string. The COUNTS() function is similar to COUNT() but operates on successive elements of a dynamic array, returning a similarly structured dynamic array of results.
Format
COUNT(string, substring) COUNTS(string, substring)
where
The COUNT() function counts occurrences of substring within string. Substrings may not overlap, thus
S = "ABABABABABAB" N = COUNT(S, "ABA")
sets N to 3.
If substring is null, COUNT() returns the length of string.
Programs compiled with the $NOCASE.STRINGS compiler directive use case insensitive string comparisons in the COUNT() and COUNTS() functions.
Example
MARKS = COUNT(REC, @FM)
This statement counts the field marks in REC.
