Numeric
The Entab switch controls how PWB converts white space on modified lines. PWB converts white space only on the lines that you modify.
The Realtabs switch must be set to no for the Entab switch to have an effect. If Realtabs is yes, white-space conversions are not performed.
The Entab switch can have the following values:
| Value | Meaning |
| 0 | Convert all white space to space (ASCII 32) characters. |
| With this setting, PWB removes tab characters on all lines that you modify. | |
| 1 | Convert white space outside quoted strings to tabs. |
| A quoted string is any span of characters enclosed by a pair of single quotation marks or a pair of double quotation marks. PWB does not recognize escape sequences because they are language-specific. | |
| For well-behaved conversions with this setting, make sure that you use a numeric escape sequence to encode quotation marks in strings or character literals. | |
| 2 | Convert white space to tabs. |
With settings 1 and 2, if the white space being considered for conversion to a tab character occupies an entire tab field or ends at the boundary of a tab field, it is converted to a tab (ASCII 9) character. The width of a tab field is specified by the Filetab switch.
In all conversions, PWB maintains the text alignment as it is displayed on screen.
