The Variable SmartĆMatching option provides matches to each part

elementĆindex or bitĆindex delimiter and the first letter or letters of
the element or bit name. Then, scroll through the variable name
choices offered. The choices offered by the variable smartĆmatching
option are determined by how many letters you type in.
Tip
D To append onto a variable name picked from the variable
smartĆmatch choices, make sure the variable name is not
selected before continuing to type.
D To reĆinitialize smartĆmatching, delete characters (by using
BACKSPACE), and reĆtype one or more.

the Editor automatically smartĆmatches on the first variable in your
variable list.

Changing a Variable's Data Type
When you enter a variable name in an instruction's input or output
parameter, a default data type is assigned based on the instruction
type. If you want to change a variable's data type to something other
than the default, you can change it by using the Variable Properties
tab.
I
MPORTANT
Changing the properties of a variable affects the variable, not just a
particular instance in which it is used. For example, if you change
the data type of a variable from timer to integer and that variable
happens to be used in a TON instruction, this integer variable will no
longer be allowed within the instruction.
