ASCII Character Table

Introduction:

ASCII is the standard format for plain text editors such as Notepad, which comes with Windows. It associates each value between 0 and 127 with a character. (This is not necessarily true of word processors, which offer fancier features like bold, italics, and a choice of fonts.)


Control Characters:

Characters 0-31 (0x00-0x1F) are control characters that are not directly displayable. Most are no longer used. Notable exceptions are:

    Dec     Hex     Char
    08      08      Backspace
    09      09      Tab
    10      0A      Line Feed
    13      0D      Carriage Return


Displayable Characters:

The following are displayable ASCII characters:

    Dec     Hex     Char
    32      20     (space)
    33      21       !
    34      22       "

Filename Forbidden Characters:

The following Bad characters are forbidden in Windows filenames. If a macro attempts to open or save a file using using one of these characters, it will be replaced by the alternate given in the Alt column:

    Dec     Hex     Bad     Alt
    34      22       "       '
    42      2A       *       # (see Notes below)
    47      2F       /       -
    60      3C       <       (
    62      3E       >       )
    63      3F       ?       ^ (see Notes below)
    58      3A       :       % (see Notes below)
    92      5C       \      & (see Notes below)
    124     7C       |       $

Notes: Colon and backslash are allowed in file paths, but not in the name portion. (Since the backslash marks a directory level, it effectively never appears in the name portion; if attempted, it specifies that the prior portion of the name should be regarded as a separate directory level. It is thus never actually replaced.)

Asterisk and question mark are allowed as "wildcards" in the name portion, but only in macro-defined search strings like '*.WAV' or 'Data?.TXT' to be used with file Open or Save dialogs. They can not be used in macros with an A. prefix to automatically load or save a specified file, such as A.Open="MyFile" or A.SaveDQA="MyFile". In such cases they will be replaced with the indicated Alt characters '#' or '^', respectively.

Period and space characters are allowed in file names, but should be used with caution.
