INTEGER IFUNC, NBUF, LCHR, MODE

C-----------------------------------------------------------------------
C PGPLOT driver for EXCL devices (Talaris)
C-----------------------------------------------------------------------
C Version 1.0 - 1989 Nov 10 - A. L. Fey.
C 2.0 - 1994 Nov 08
C-----------------------------------------------------------------------
C
C Supported device: Any Talaris printer that accepts the EXCL
C page description language. 7-bit mode is used.
C
C Device type code: /EXCL (landscape)
C /VEXCL (portrait)
C
C Default file name: pgplot.explot.
C
C Default view surface dimensions: 10.25 inches horizontal x 7.75 inches
C vertical (landscape mode).
C Default view surface dimensions: 7.75 inches horizontal x 10.25 inches
C vertical (portrait mode).
C
C Resolution: The driver uses coordinate increments of 1/1000 inch.
C The true resolution is device-dependent; at time of
C writing, it is typically 300 dots per inch.
C
C Color capability: Color indices 0 (erase), and 1 (black) are
C supported. Requests for other color indices are
C converted to 1. It is not possible to change color
C representation.
C
C Input capability: None.
C
C File format: Ascii, variable length records (max 80 bytes).
