The MACONTROL Procedure

Syntax

The syntax for the INSET statement is as follows:

INSET keyword-list </ options> ;

You can use any number of INSET statements in the MACONTROL procedure. Each INSET statement produces a separate inset and must follow an EWMACHART or MACHART statement. The inset appears on every panel (page) produced by the last chart statement preceding it.

Keywords specify the statistics to be displayed in an inset; options control the inset’s location and appearance. A complete description of the INSET statement syntax is given in the section Syntax of Chapter 13, The SHEWHART Procedure. The INSET statement options are identical in the MACONTROL and SHEWHART procedures, but the available keywords are different. The options are listed in Table 13.87. The keywords available with the MACONTROL procedure are listed in Table 9.14 to Table 9.17.
