What Are Batch Variables
What What Are Batch Variables?
Batch variables are variables that create, store value to and retrieve value from in a batch file.
There are 3 ways a batch variable is defined:
1. Defined in the batch file using the "set" command. For example, "set java_home=\fyicenter\java" will define a new variable, "%java_home%".
2. Defined as system enviroment variables before the batch being executed. For example, "%path%" is a variable defined as a system enviroment variable.
3. Defined as batch execution context built-in variables. For example, "%random% is a batch built-in variable that represents a random integer.
