Append procedure
DECLARATION: Append(var F : Text);
PURPOSE: Opens an existing file for appending.
UNIT: System
REMARKS: Where F is a Text-File variable that must have been
associated with an existing external file using Assign.
If a CTRL-Z (ascii 26) is present in the last 128 byte
block of the file, the current file position is set to
overwrite the first CTRL-Z in the block. This allows
for text to be appended to a file that terminates with a
CTRL-Z.
If F was assigned an empty name, such as Assign(F,''),
after the call to Append, F will refer to the standard
output file (standard handle number 1).
After a call to Append, F becomes Write-Only, and the
pointer is positioned at the end of the file.
NOTE: With {$I-}, errors are returned through IOResult
