#number
number
Number of characters for new tab stops. The valid range for number is 1–19.
The Tab Set (#) command sets the width in spaces that the CodeView debugger fills for each tab character. The default tab is eight spaces. You can specify values in the range 1–19.
You may want to set a smaller tab size if your source code has so many levels of indentation that source lines extend beyond the edge of the screen.
This command has no effect if your source code contains no tab characters.
