RTrim

Declare Function RTrim ( ByRef str As Const String, [ Any ] ByRef trimset As Const String = " " ) As String
Declare Function RTrim ( ByRef str As Const WString, [ Any ] ByRef trimset As Const WString = WStr(" ") ) As WString

result = RTrim[$]( str [, [ Any ] trimset ] )

str
trimset

Returns the trimmed string.

This procedure trims surrounding characters from the 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.

Dim s1 As String = "Article 101  "
Print "'" + RTrim(s1) + "'"
Print "'" + RTrim(s1, " 01") + "'"
Print "'" + RTrim(s1, Any " 10") + "'"

Dim s2 As String = "Test Pattern aaBBaaBaa"
Print "'" + RTrim(s2, "Baa") + "'"
Print "'" + RTrim(s2, Any "Ba") + "'"

will produce the output:

'Article 101'
'Article 101  '
'Article'
'Test Pattern aaB'
