     pnch - file format	for card images

DESCRIPTION    [Toc]    [Back]

     The PNCH format is	a convenient representation for	files consisting of
     card images in an arbitrary code.

     A PNCH file is a simple concatenation of card records.  A card record
     consists of a single control byte followed	by a variable number of	data
     bytes.  The control byte specifies	the number (which must lie in the
     range 0-80) of data bytes that follow.  The data bytes are	8-bit codes
     that constitute the card image.  If there are fewer than 80 data bytes,
     it	is understood that the remainder of the	card image consists of
     trailing blanks.
