Tab-Format

The tab-format source lines are defined as follows: @

• A tab in any of columns 1 through 6, or an ampersand in column 1, establishes the line as a tab-format source line.

• If the tab is the first nonblank character, the text following the tab is scanned as if it started in column 7.

• A comment indicator or a statement number can precede the tab.

• Continuation lines are identified by an ampersand (&) in column 1, or a nonzero digit after the first tab.
