TRIM


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

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

Usage:
result = Trim[$]( 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) and right (end) 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 = " ... Stuck in the middle ... "
Print "'" + Trim(s1) + "'"
Print "'" + Trim(s1, Any " .") + "'"

Dim s2 As String = "BaaBaaaaB With You aaBBaaBaa"
Print "'" + Trim(s2, "Baa") + "'"
Print "'" + Trim(s2, Any "Ba") + "'"
will produce the output:

'... Stuck in the middle ...'
'Stuck in the middle'
'aaB With You aaB'
' With You '
