FILECLOSE

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

Syntax

FILECLOSE fileunit

Arguments

fileunit

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

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 9-119 Program That Opens and Closes a File

Suppose you have a program called READFILE that takes a file name as its first argument. The following lines from the program open the file and then close it.

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