Data Types for Command Variables

You can use the following data types for the variables in a command string:

Data type	Description
Strings	String data types are delimited by leading and trailing white spaces and quotation marks. MCI removes single quotation marks from a string. To put a quotation mark in a string, use a set of two quotation marks where you want to embed your quotation mark. To use an empty string, use two quotation marks delimited by leading and trailing white spaces.
Signed long integers	Signed long integer data types are delimited by leading and trailing white spaces. Unless otherwise specified, integers can be positive or negative. If you use negative integers, you should not separate the minus sign and the first digit with a space.
Rectangles	Rectangle data types are an ordered list of four signed short values. White space delimits this data type and separates each integer in the list.
