This manual presents terms that represent keywords, information you supply, and

identifiers as follows:

Keywords are shown in uppercase in text and in examples. For instance, the

keyword SOURCE appears in an example as follows:

?SOURCE . . .

Identifiers are shown in lowercase in examples and in uppercase in example

comments and in text. For instance, the identifier TOTAL appears in an example

as follows:

INT total;

Terms that represent user-specified information are shown in lowercase italics.

For instance, when you declare a variable, you specify an identifier.

Some of the examples in this manual include diagrams that illustrate memory

allocation. The diagrams are two bytes wide. Unless otherwise noted, the diagrams

refer to locations in the primary area of the user data segment. The following example

shows allocation of an INT(32) array and its initializing values. In the diagram, solid

lines depict borders of storage units, in this case doublewords. Short lines depict

words within each doubleword:

INT(32) c[0:4] :=

["abcd", 1D, 3D, "XYZ ", %20D];
