        This  package  comes  from      http://Amiga.SourceForge.net

----------------------------------------------------------------------------

bc  is  an  arbitrary  precision  numeric  processing  language.  Syntax is
similar  to  C,  but  differs  in  many  substantial  areas.   It  supports
interactive execution of statements.  bc is a utility included in the POSIX
P1003.2/D11 draft standard.

This  version was written to be a POSIX compliant bc processor with several
extensions  to  the  draft  standard.   Option flags are available to cause
warning  or  rejection  of the extensions to the POSIX standard.  For those
who  want  only  POSIX  bc  with  no  extensions, a grammar is provided for
exactly  the language described in the POSIX document.  The grammar (sbc.y)
comes  from  the  POSIX document.  The Makefile contains rules to make sbc.
(for Standard BC)

Since  the POSIX document does not specify how bc must be implemented, this
version  does  not use the historical method of having bc be a compiler for
the dc calculator.  This version has a single executable that both compiles
the  language and runs the a resulting "byte code".  The "byte code" is NOT
the dc language.

Also,  included  in the initial distribution is the library file vfprintf.c
for  MINIX systems.  My minix 1.5 did not have this file.  Also, you should
verify that vsprintf.c works correctly on your system.

The  extensions  add  some features I think are missing.  The major changes
and  additions  for  bc  are  (a)  names are allowed to be full identifiers
([a-z][a-z0-9_]*),  (b)  addition  of  the  &&,  ||,  and !  operators, (c)
allowing  comparison and boolean operations in any expression, (d) addition
of  an  else  clause  to  the  if statement, (e) addition of a new standard
function "read()" that reads a number from the standard input under program
control,  (f)  passing of arrays as parameters by variable, (g) addition of
the  "halt" statement that is an executable statement unlike the quit (i.e.
"if  (1 == 0) quit" will halt bc but "if (1 == 0) halt" will not halt bc.),
and  (h)  the  addition of the special variable "last" that is assigned the
value     of     each     print     as     the     number    is    printed.
