.SH DESCRIPTION
The \fBior()\fP function performs a bitwise logical \fBOR\fP of the \fBa\fP and \fBb\fP
operands. The result is placed at address \fBc\fP. The contents of memory at \fBa\fP and
\fBb\fP are not changed, the previous memory content at \fBc\fP is lost. The parameter
\fBnb\fP defines the size of the operands (in bytes) located at addresses \fBc\fP,
\fBa\fP, \fBb\fP.
.PP
The function affects the flags \fBC\fP, \fBO\fP, \fBP\fP, \fBS\fP, \fBZ\fP.
.PP
The \fBA\fP flag is undefined. The \fBP\fP flag is set only when the size of the \fBa\fP,
\fBb\fP operands is equal to one or two bytes (\fBnb\fP == 1 || \fBnb\fP == 2).
