CountLeft()

CountLeft()

Count a certain character at the beginning of a string

Syntax

       CountLeft( <cString>, [<cSearch|nSearch>] ) -> nCount

Arguments

<cString> Designates the character string in which the <cCharacter|nCharacter> character is counted.

<cSearch|nSearch> Designates the character at the beginning of the <cString> that is counted. The default value is a space, CHR(32).

Returns

CountLeft() returns the number of <cSearch|nSearch> characters that appear in an uninterrupted sequence at the beginning of <cString>.

Description

While RemLeft() removes leading characters from the <cString>, CountLeft() only determines the number of leading <cSearch|nSearch> characters appearing in an uninterrupted sequence at the beginning of the <cString>.

Examples

       .  Count the blanks:
              ? CountLeft("   123")               // Result: 3
           .  Count the "." characters:
              ? CountLeft("..4.123", ".")         // Result: 2
           .  In this example, there is nothing to count:
              ? CountLeft("123456")               // Result: 0
