Format
CLOSE number1
Description
This function closes the file number identified by number1. If an error is
returned by DOS, the system variable "ERROR" will be > 0.
Example
CLOSE 1
IF ERROR > 0 THEN CHECKERROR:
After successful execution of the CLOSE statement, the file previously
opened as file 1 will be closed. If an error is returned by DOS, the
ERROR variable will be set by ASIC to a non-zero value.
Comments
If you fail to close an open file (which was opened for writing), you may
lose data, since file i/o is buffered, and the last buffer may not have
been flushed.
Also, number1 may only be a constant with the value of 1-3.
