InOutRes

Result of last I/O operation.

Declaration

Source position: systemh.inc line 760

var InOutRes: Word;

Description

InOutRes contains the result of the last I/O operation using one of the file I/O routines. When I/O checks are enabled, this variable is checked and if it is nonzero, a runtime error is raised.

Although it is a variable for historical reasons, it is not meant to be written to by user code, outside of routines that implement some form of file I/O.
