PPWIZARD is a free preprocessor for HTML, REXX, Visual Basic or any text files.

Switch /DebugChars:List

This is a PPWIZARD command line switch. You can set up your own default switches in the "PPWIZARD_OPTIONS" environment variable or in project files.

This switch allows you to modify the following debug 'markers':

1. Left Quote
   This allows you to change the way ppwizard displays a left "quote" in debug mode.

2. Right Quote
   This allows you to change the way ppwizard displays a right "quote" in debug mode.

3. New Line
   This allows you to change the way ppwizard displays a new line character.

If the supplied list is empty then the defaults are restored otherwise it specifies the values for as many comma seperated items as are supplied in the list (items assigned in the order shown above).

An item can be:

• A value of "-1" means use an empty string (no characters).

• A decimal number is the ASCII code of the single character you wish.

• Anything else is a character or characters that you wish. This can of course include normal command line hexadecimal codes.

This switch can be handy as the default characters could easily be misread as normal characters. If your viewer supports some of the extended characters (below the space or above ASCII 127) then this can make debug output much easier to read.

Display List In Your Viewer

The following code allows you to create a list of possible codes for you to examine in the particular viewer that you will be using to look for good distinct characters. These will/may have to be changed if you change your viewer.

Just cut and paste the following:

    #define    DisplayX  call Say left(d2c(x),6) || left(x,9) || '{x' || d2x(x) || '}'
    #DefineRexx ''
       ;--- Title ---------------------------------------------------------------
       call Say '';
       call Say 'CHAR  DECIMAL  HEX STRING'
       call Say '~~~~  ~~~~~~~  ~~~~~~~~~~'
    
       ;--- Do all but ASCII code 0 and 9, 10,13 --------------------------------
       do  x = 1 to 255
           if  x <> 9 & x <> 10 & x <> 13 then
           do
               <$DisplayX>
           end;
       end;
    
       ;--- Now do ASCII 0 (some editors/viewers will NOT HANDLE THIS!) ---------
       x = 0; <$DisplayX>
       call Say '';
    #DefineRexx
    

EXAMPLE

The following characters look good in the version of notepad I'm using.
