Editing Integer BASIC (section)

===Input/output===
Integer BASIC lacked any custom input/output commands, and also lacked the {{code|DATA}} statement and the associated {{code|READ}}. To get data into and out of a program, the input/output functionality was redirected to a selected [[Expansion card|card slot]] with the {{code|PR#x}} and {{code|IN#x}}, which redirected output or input (respectively) to the numbered slot. From then on, data could be sent to the card using conventional {{code|PRINT}} commands and read from it using {{code|INPUT}}.{{sfn|Raskin|1978|p=120}}
