  ' DESCRIPTION
  '     Replace a string or specific character(s) within a string. This routine
  '     can also be used to strip characters.
  '
  ' ARGUMENTS
  '     StrOriginal    = String to work on.
  '
  '     StrFind     defines string to search for.
 
  '     StrReplace     = New character (or string) to substitute.
  '
  '     intOPMode  = Sets operation by defining the "replace" mode and "compare"
  '                  mode. Valid parameters are:
  '
  '                  BinaryCompare (Case sensitive. Default if not specified.)
  '                  TextCompare (Not case sensitive)
  '                  DataBaseCompare (Microsoft Access data compare)
  '
  '    Updated = Optional. Returns positive if string was modified. Value is number
  '                  of replacements made.
  '
  ' RETURNS
  '     Returns new string.
  '
  ' DEPENDENCIES
  '     None
  '
  ' REMARKS
  '     To strip a string of character(s), set StrReplace to vbNullString or "".
