COUNT
Syntax
COUNT(str.expr1, str.expr2)
Description
The UniBasic COUNT function returns the number of times a substring appears
within a string. The string you want to search, str.expr1, must be longer than the
substring str.expr2. After str.expr2 is found, the system searches the string again with
the new starting point after the entire first occurrence of str.expr2. If str.expr2 is not
found, the COUNT function returns 0. COUNT supports multibyte languages.
Note: In BASICTYPEs P and M, after UniData finds str.expr2, it searches the string
again with the new starting point after the first character of the first occurrence of
str.expr2. UniData can find overlapping character strings.
Parameters
The following table describes each parameter of the syntax.
Parameter Description
Examples
In the following example, the program segment searches the string STRING for the
