WRITES(channel, data_area[, label][, GETRFA:new_rfa]) [[error_list]]
The channel on which the file is open. The channel must already have been opened in output, append, or update mode. (n)
An expression that contains the information to be written. (a)
(optional) The label to which control is transferred if the output device is full.
(optional) Returns the record’s RFA after the WRITES has been performed. See GETRFA for a complete description.
(optional) An I/O error list. If any one of the specified errors occurs as part of the WRITES, control is transferred to the associated label.
The WRITES statement is only supported for non-ISAM files.
The WRITES statement writes the record immediately following the most recent record that was read from or written to the output file to a specified channel. It also appends a record terminator to the data area written.
After the WRITES, any automatic record locks are released.
When using xfServer, setting the SCSPREFETCH environment variable turns on record buffering for the WRITES statement.
If you have a telnet terminal connection, see $ERR_IOFAIL for more information.
The following example scans through a file, extracting the name field into a separate list file.
subroutine find_rec a_chn ,d ;Input file channel .include "REC:who.rec" ;Record "who" includes field "name" .define TMPCHN ,99 record list_file ,a*, "WRK:name.lst" proc xcall flags(4020, 1) open(TMPCHN, o, list_file) repeat begin reads(a_chn, who, done) writes(TMPCHN, name) end done, close TMPCHN xreturn endsubroutine
