LTRIM


Removes surrounding substrings or characters on the left side of a string

Syntax:
declare function Ltrim ( byref str as const string, [ Any ] byref trimset as const string = " " ) as string
declare function Ltrim ( byref str as const wstring, [ Any ] byref trimset as const wstring = Wstr(" ") ) as wstring

Usage:
result = Ltrim[$]( str [, [ Any ] trimset ] )

Parameters:
str
The source string.
trimset
The substring to trim.

Return Value:
Returns the trimmed string.

Description:
This procedure trims surrounding characters from the left (beginning) of a source string. Substrings matching trimset will be trimmed if specified, otherwise spaces (ASCII code 32) are trimmed.

If the Any keyword is used, any character matching a character in trimset will be trimmed.

All comparisons are case-sensitive.

Examples:
Dim s1 As String = "  101 Things to do."
Print "'" + LTrim(s1) + "'"
Print "'" + LTrim(s1, " 01") + "'"
Print "'" + LTrim(s1, Any " 01") + "'"

Dim s2 As String = "BaaBaaBAA Test Pattern"
Print "'" + LTrim(s2, "Baa") + "'"
Print "'" + LTrim(s2, Any "BaA") + "'"
will produce the output:

'101 Things to do.'
'  101 Things to do.'
'Things to do.'
'BAA Test Pattern'
' Test Pattern'
