S Code - Substitution

The S (Substitution) code specifies two elements to be used for substitution.

• If the input to this code is not zero or null, the processor substitutes the first element for the value.
• If the input to this code is zero or null, the processor substitutes the second element for the value.

Each of these substitution elements can be the value of a specified attribute, a literal or the input to this code.

Input Conversion

Input conversion does not invert. It simply processes the input data.

Syntax

S;value-substitute;zero-substitute

Syntax Elements

value-substitute is the element that the processor substitutes for data that is not zero or null.

zero-substitute is the element that the processor substitutes for data that is zero or null.

Elements

The elements that you can use for value-substitute or for zero-substitute are:

• The AMC of an attribute, the value of which will be used.
• A literal enclosed in single or double quotes.
• An asterisk (*) to specify the input to this code.
