The SHOWTABS directive in INI.VUE and command mode allows embedded TAB characters to be represented in the display by some other character. The argument can be boolean (in which case the default is to use a lower case "t"), or it can be the ASCII value of the character to use (in decimal, hex or octal notation). It also accepts the special value ">>" to use the right guillemet (aka double right chevron) character (requires ANSI/Latin1 character set). Examples:
>SHOWTABS
enables feature using "t"
>SHOWTABS OFF
disables feature
>SHOWTABS >>
use the ">>" character
>SHOWTABS 20
use ASCII 20 (^T)
Note that in all cases, the character used will be dim to hopefully distinguish it from the normal text characters. Also, ASCII values between 1-31 are displayed like control characters, i.e. 1 displays as a dim "A", 20 as a dim "T", etc.
