Functions by Data Type
Section 4, Expressions, explains how the data type of an operand affects its behavior
in expressions.
Addresses as Data
You can store standard (16-bit) addresses in INT variables. Use only unsigned
operations for standard addresses.
You can store extended (32-bit) addresses in INT(32) variables.
Functions by Data Type
The data type of a variable determines the standard function you can use with the
variable. Table 3-4 lists the function categories by data type.
For more information on the descriptions of each standard function, see Section 14,
Standard Functions.
