Chapter 16: Line Printer Graphics

Usage Notes

The routine names in this chapter end with the letter “P” to indicate line printer plotting and every routine starts printing at the beginning of a new page.

Depending on the nature of plots, some routines allow the user to change page width and/or length. This capability is specified in each routine and, if allowed, can be done by calling the routine PGOPT (see Chapter 19, Utilities;) in advance. To change the page width, the user should make the following call to PGOPT:

CALL PGOPT(1, IPAGEW)

where IPAGEW indicates the page width in columns. To change the page length, the user should make the following call to PGOPT:

CALL PGOPT(2, IPAGEL)

where IPAGEL indicates the page length in rows. See the PGOPT document for more information.
