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

Parameters

Name		Description
`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.

Remarks

Usage

Platform Differences

DOS version/target of FreeBASIC does not support the wide-character version of LTrim.

Dialect Differences

The string type suffix "$" is required in the -lang qb dialect.
The string type suffix "$" is optional in the -lang fblite dialect.
The string type suffix "$" is ignored in the -lang fb dialect, warn only with the -w suffix compile option (or -w pedantic compile option).

Differences from QB

QB does not support specifying a trimset string or the ANY clause.

Example

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'
