NAME
pnch - file format for card images
DESCRIPTION
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.
