.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
.IP "setEvenParity \s-1LIST\s0" 8
.IX Item "setEvenParity LIST"
Copies the elements of \s-1LIST\s0 to a new list and converts the new elements to
strings of bytes with even parity. In array context returns the new list.
In scalar context joins the elements of the new list into a single string
and returns the string.
.IP "setOddParity \s-1LIST\s0" 8
.IX Item "setOddParity LIST"
Like setEvenParity function, but converts to strings with odd parity.
.IP "setSpaceParity \s-1LIST\s0" 8
.IX Item "setSpaceParity LIST"
Like setEvenParity function, but converts to strings with space
(High bit cleared) parity.
.IP "setMarkParity \s-1LIST\s0" 8
.IX Item "setMarkParity LIST"
Like setEvenParity function, but converts to strings with mark
(High bit set) parity.
.IP "EvenBytes \s-1LIST\s0" 8
.IX Item "EvenBytes LIST"
Returns the number of even parity bytes in the elements of \s-1LIST.\s0
.IP "OddBytes \s-1LIST\s0" 8
.IX Item "OddBytes LIST"
Returns the number of odd parity bytes in the elements of \s-1LIST.\s0
.IP "SpaceBytes \s-1LIST\s0" 8
.IX Item "SpaceBytes LIST"
Returns the number of space parity bytes in the elements of \s-1LIST.\s0
.IP "MarkBytes \s-1LIST\s0" 8
.IX Item "MarkBytes LIST"
Returns the number of mark parity bytes in the elements of \s-1LIST.\s0
.IP "isEvenParity \s-1LIST\s0" 8
.IX Item "isEvenParity LIST"
Returns \s-1TRUE\s0 if the \s-1LIST\s0 contains no byte with odd parity, \s-1FALSE\s0 otherwise.
.IP "isOddParity \s-1LIST\s0" 8
.IX Item "isOddParity LIST"
Returns \s-1TRUE\s0 if the \s-1LIST\s0 contains no byte with even parity, \s-1FALSE\s0 otherwise.
.IP "isSpaceParity \s-1LIST\s0" 8
.IX Item "isSpaceParity LIST"
Returns \s-1TRUE\s0 if the \s-1LIST\s0 contains no byte with mark parity, \s-1FALSE\s0 otherwise.
.IP "isMarkParity \s-1LIST\s0" 8
.IX Item "isMarkParity LIST"
Returns \s-1TRUE\s0 if the \s-1LIST\s0 contains no byte with space parity, \s-1FALSE\s0 otherwise.
.IP "showParity \s-1LIST\s0" 8
.IX Item "showParity LIST"
Like setEvenParity function, but converts bytes with even parity to 'e'
and other bytes to 'o'.
The function showParity must be imported by a specialised import list.
.IP "showMarkSpace \s-1LIST\s0" 8
.IX Item "showMarkSpace LIST"
Like setEvenParity function, but converts bytes with space parity to 's'
and other bytes to 'm'.
The function showMarkSpace must be imported by a specialised import list.
