If the Test parameter is a word or long word address, the Low Limit
and High Limit parameters can be either a constant, a word, or a
long word address.
When mixed-sized parameters are used, all parameters are put into the
format of the largest parameter. For instance, if a word and a long word
are used, the word is converted to a long word.
The data ranges are:
•
-32,768…32,767 (word)
•
-2,147,483,648…2,147,483,647 (long word)
Addressing Modes and File Types can be used as shown in the following
table:
LIM Instruction Valid Addressing Modes and File Types
For definitions of the terms used in this table see Using the Instruction Descriptions on page 92.
