The command for output is "echo".
To take input, use the command "set /p variablename=prompt text here"
VARIABLES: INFO
Variables are sections memory in a computer that can store data. They can be addressed in whatever language you use by what is called an identifier. In our case, the identifier is what is in between the "%" signs. Until later, we will only be using string input (specified by the /p" which records a series (or array) or characters until an end-of-line character (enter) is detected.
So when a variable is created, memory is allocated (cleared and/or assigned) for the variable name. So when your program refers to your variable name (for example purposes, say it is "myvar") myvar, it requests from memory whatever is stored in the memory allocated to "myvar". If the user had entered "herpderp" and you called myvar, then it would load the series of characters "herpderp" into memory.
