Using

in Program-Described Files

An overflow

indicator

(OA through

OG,

is set on when the last lin

An

can be used to

to

program-described

PRINTER files and are used primarily to condition th

heading lines.

An

overflow indicator is specified using the keyword O

to condition

specifications

(positions 9 through 11) and output specificatio

through

If

unused overflow indicator to the PRINTER file. Overflow indicators can specified as resulting indicators on the calculation specifications (p through 76).

The compiler sets on an overflow indicator only the first time an ove occurs on a page. An overflow condition exists whenever one of the occurs:

¹ A line is printed past the overflow line.

¹ The overflow line is passed during a space operation.

¹The overflow line is passed during a skip operation.

Table 23 on page 319	shows	the results	of	the presence or absence
flow indicator on the	file	description	and	output specifications.

The following considerations apply to overflow indicators used on the specifications:

¹ Spacing past the overflow line sets the overflow indicator on.
