NAME

Files - file handling

SYNOPSIS

TYPE FILE = StdIO.FILE;



VAR Done: BOOLEAN;



PROCEDURE OpenRead(VAR f: FILE; filename: ARRAY OF CHAR);
PROCEDURE OpenWrite(VAR f: FILE; filename: ARRAY OF CHAR);
PROCEDURE Close(f: FILE);
PROCEDURE SetPos(f: FILE; pos: LONGCARD);
PROCEDURE GetPos(f: FILE; VAR pos: LONGCARD);
PROCEDURE Reset(f: FILE);
PROCEDURE Delete(filename: ARRAY OF CHAR);
PROCEDURE Rename(oldname, newname: ARRAY OF CHAR);

DESCRIPTION

OpenRead and OpenWrite open the file named filename for reading/writing and return the filepointer f.

Close causes any buffers for the named stream to be emptied, and the file to be closed.

GetPos and SetPos get/set the position of the filepointer f. Reset is equivalent to SetPos(f, 0).

Delete and Rename are self-explanatory.

DIAGNOSTICS

Done is TRUE on successful calls, otherwise FALSE.
