Numeric
The Tabdisp switch specifies the decimal ASCII code of the character used to display tab (ASCII 9) characters in your file. If you specify 0 or 255, PWB uses the space (ASCII 32) character.
It is sometimes useful to set Tabdisp to the code for a graphic character so that tabs can be distinguished from spaces.
Tabdisp:32
The default value 32 specifies the ASCII space character.
