tabsize

Syntax

    -qtabsize=n 

Purpose
Changes the length of tabs as perceived by the compiler.

Notes
n is the number of character spaces representing a tab in your source program.

This option only affects error messages that specify the column number at which an error occurred. For example, the compiler will consider tabs as having a width of one character if you specify -qtabsize=1. In this case, you can consider one character position (where each character and each tab equals one position, regardless of tab length) as being equivalent to one character column.
