bc: Description
1.1 Description
===============
'bc' [ -hlwsqv ] [long-options] [ FILE ... ]
'bc' is a language that supports arbitrary precision numbers with
interactive execution of statements. There are some similarities in the
syntax to the C programming language. A standard math library is
available by command line option. If requested, the math library is
defined before processing any files. 'bc' starts by processing code
from all the files listed on the command line in the order listed.
After all files have been processed, 'bc' reads from the standard input.
All code is executed as it is read. (If a file contains a command to
halt the processor, 'bc' will never read from the standard input.)
This version of 'bc' contains several extensions beyond traditional
'bc' implementations and the POSIX draft standard. Command line options
can cause these extensions to print a warning or to be rejected. This
document describes the language accepted by this processor. Extensions
will be identified as such.
The author would like to thank Steve Sommars
(<Steve.Sommars@att.com>) for his extensive help in testing the
implementation. Many great suggestions were given. This is a much
better product due to his involvement.
