Installing `gawk' on a Tandem
-----------------------------

   The Tandem port is only minimally supported.  The port's contributor
no longer has access to a Tandem system.

   The Tandem port was done on a Cyclone machine running D20.  The port
is pretty clean and all facilities seem to work except for the I/O
piping facilities (Note: Using `getline' from a Pipe.,
*Note Using `getline' into a Variable from a Pipe:
Getline/Variable/Pipe, and Note: Redirecting Output of `print' and
`printf', which is just too foreign a concept for Tandem.

   To build a Tandem executable from source, download all of the files
so that the file names on the Tandem box conform to the restrictions of
D20.  For example, `array.c' becomes `ARRAYC', and `awk.h' becomes
`AWKH'.  The totally Tandem-specific files are in the `tandem'
"subvolume" (`unsupported/tandem' in the `gawk' distribution) and
should be copied to the main source directory before building `gawk'.

   The file `compit' can then be used to compile and bind an executable.
Alas, there is no `configure' or `make'.

   Usage is the same as for Unix, except that D20 requires all `{' and
`}' characters to be escaped with `~' on the command line (but _not_ in
script files). Also, the standard Tandem syntax for `/in filename,out
filename/' must be used instead of the usual Unix `<' and `>' for file
redirection.  (Redirection options on `getline', `print' etc., are
supported.)

   The `-mr VAL' option (Note: Command-Line Options.)  has
been "stolen" to enable Tandem users to process fixed-length records
with no "end-of-line" character. That is, `-mr 74' tells `gawk' to read
the input file as fixed 74-byte records.
