Platform Differences

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

Dialect Differences

• Not available in the -lang qb dialect unless referenced with the alias __Trim. 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).

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 ...'
