Description:
PUT writes a record from a field variable(s) declared by the FIELD statement to a data file
specified by filenumber.
filenumber is the number of a data file opened by the OPEN statement.
recordnumber is the record number where the data is to be placed in a data file.
It should be within the range from 1 to the maximum number of registrable records
(filelength) specified by the OPEN statement (when a new data file is created).
• If recordnumber option is omitted, the default record number is one more than the last
record written.
Record numbers to be specified do not have to be continuous. If you specify record
number 10 when records 1 through 7 have been written, for example, then the PUT
statement automatically creates records 8 and 9 filled with spaces and then writes data
to record 10.
If the actual data length of a field variable is longer than the field width specified by the
FIELD statement, then the excess is truncated from the right end column.
Since data in a data file is treated as text data (ASCII strings), numeric data should be
converted into the proper string form with the STR$ function before being assigned to a
field variable.
• The PUT statement cannot write data to files opened as read-only by specifying drive B
in the OPEN statement.
