Text
The Tabstops switch specifies variable tab stops used by the Tab and Backtab functions. Tab moves the cursor to the next tab stop; Backtab moves the cursor to the previous tab stop.
Note that the Tabstops switch has no effect on the handling of tab (ASCII 9) characters in a file.
Tabstops: [[tabwidth]]...repeat
tabwidth
The width of a tab stop. You can repeat tabwidth for as many tab stops as will fit on a PWB line (250 characters).
repeat
The width of every tab stop after the explicitly listed tab stops.A value of 0 for repeat specifies that there are no tab stops after the list of tabwidth settings. When the cursor is past the last tab stop, the Tab function does nothing.
Tabstops:4
In PWB 1.x, Tabstops is a numeric switch specifying a single value, equivalent to the repeat value in PWB 2.0. The default PWB 2.00 Tabstops setting mimics the default behavior of PWB 1.x.
The Tabstops switch setting
Tabstops:4
sets a tab stop every four columns.

The setting
