Statement PUT

Write one byte to the open OUTPUT file.

Syntax

PUT expression

Parameters

Parameter	Meaning
`expression`	Integer in the inclusive range 0–255.

Behavior

Accumulates bytes in a 256-byte buffer. Full sectors are sent to the verified writer; CLOSE or END flushes the final partial sector. The total supplied bytes must match the length declared in OPEN.

An out-of-range byte produces status 35. Too little or too much output prevents successful publication; previously committed file versions are preserved.

Example

10 OPEN "digits",OUTPUT,3
20 PUT 49:PUT 50:PUT 51
30 CLOSE
40 END

Limits and diagnostics

Requires an OUTPUT data file. This writes binary bytes, not decimal formatting or automatic line endings.

Status-code reference.
