PUT

Syntax

PUT [#]<file number>[,<record number>]

Versions: Disk

Purpose

To write a record from a random buffer to a random file.

Remarks

is the number under which the file was OPENed. If is omitted, the record will have the next available record number (after the last PUT). The largest possible record number is 32767. The smallest record number is 1.

Example

10 OPEN "R", 1, "INVENTORY.DAT", 128
20 FIELD #1, 20 AS ITEM$, 4 AS PRICE$, 2 AS QTY$
30 LSET ITEM$ = "Widget"
40 LSET PRICE$ = MKS$(29.95)
50 LSET QTY$ = MKI%(100)
60 PUT #1, 5  ' Write to record 5
70 CLOSE #1

Note: PRINT#, PRINT# USING, and WRITE# may be used to put characters in the random file buffer before a PUT statement. In the case of WRITE#, BASIC-80 pads the buffer with spaces up to the carriage return. Any attempt to read or write past the end of the buffer causes a "Field overflow" error.
