FILECLOSE

The FILECLOSE command closes an open file. When the file has not been opened, an error occurs.

Syntax

FILECLOSE fileunit

Parameters

fileunit: An INTEGER fileunit number assigned to an open file by a previous call to the FILEOPEN function or by an OUTFILE command.

Usage Notes

LOG Command

You must use the LOG command with the EOF keyword, rather than FILECLOSE, to close a file that was opened with the LOG command.

Examples

Example 9-120 Program That Opens and Closes a File

fil.unit = FILEOPEN(arg(1), read)
   ... (Commands to read and process data)
FILECLOSE fil.unit
