The READ command reads data from the DATA block. The READ command is another way of assigning a value to a variable. The data that is assigned to the variables must already be present in the program in the form of DATA lines. The position in the DATA block is recorded in a pointer. The pointer is reset to the beginning of the DATA block with the RESTORE command.
Example
DATA 1,2,3, APPLE, "GCWIZARD", "CACHE", "WITH,COMMA"
READ A
READ B, C
