The CPT instruction performs copy, arithmetic, logical, and conversion
operations. You define the operation in the Expression and the result is
written in the Destination. The CPT uses functions to operate on one or
more values in the Expression to perform operations such as:
• converting from one number format to another.
• manipulating numbers.
• performing trigonometric functions.
The execution time of a CPT instruction is longer than a single arithmetic

operation and uses more instruction words.
Enter the following parameters when programming this instruction:
• Expression is zero or more lines, with up to 28 characters per line,
up to 255 characters.
• Destination is a word address or the address of a floating-point data
element.
