 fpl.library v6.0
 ================

 Frexx Programming Language (FPL) is an interpreting script/macro language
 shared library, designed to be flexible and easy inserted in any code.

 FPL is a complete script programming language _very_ similar to C. If you
 are a software developer and plans to add any kind of macro/script control,
 consider the FPL alternative!

 fpl.library lets the software programmer define functions that FPL should
 accept. The library will call a function in the software whenever any of
 these functions are used in an FPL program.

 The programming language features include:

   o Full ANSI C syntax statements with semicolon separations.

   o String, integer/long, char and short variables, including
     multidimensional arrays.

   o 100% ANSI C operator precedence and expression syntax.

   o C and C++ style comments.

   o A subset of the ANSI C function declaration and prototyping syntax and
     concepts. The use of functions is exactly as C.

   o Fully recursive, fully re-entrant.

   o Local/global variable levels just as in ANSI C. Global variables can be
     global within this particular file, or cross-file.

   o As an extension to C, local and global functions. Global functions can
     also be either system-wide or single file accessible.

   o Enhanced (from ANSI C) array compound assigns.

   o while, for, if, do, break, continue, else, int, exit, char, long,
     register, auto, volatile, typedef, const and return are 100% ANSI C
     compatible. 'while' has been extended with an 'else' support and 'break'
     with a multi level break option.

   o Octal, decimal, binary and decimal numbers are all easily used and mixed
     as in C; and for those parts not existing in C, likewise syntax.

   o A number of internal functions which include: strcmp, strncmp, strstr,
     atoi, strtol, strlen, abs and the FPL specific substr, eval, ltostr and
     interpret.

   o Supports the preprocessor instruction "#line" enabling FPL to run
     common C preprocessor output.

 Library features include:

   o Interpreting common ASCII text files. Create the programs in your
     favourite editor.

   o 100% real-time.

   o Using an own stack without charging the host process' stack, including
     extensive and exclusive stack expanding possibilies, controllable by the
     library programmer.

   o Full function argument parsing, you don't have to do more than reading
     them from the array FPL supplies you with.

   o Easily compiled to a shared library under AmigaDOS, UNIX and OS/2.
     Compiled to link library under any modern operating system featuring an
     ANSI C compiler. (It has beeen successfully compiled under AIX, SunOS,
     Dell UNIX, HPUX and OS/2.)

   o Source code available enables fast ports to other operating systems.

   o fpl.library is smaller than 40KB (amiga version)/60KB (OS/2 version).

   o Very dynamic function adding and deleting possibilities.

   o Dynamic program design. Small FPL programs will demand very little memory
     to run.

   o Demands less additional code than ARexx equivalences.

   o All library functions are fully re-entrant.

   o Deals with direct function calls instead of message port overhead, but
     can easlily be made to do so if wanted.

   o Resource tracking. All memory used/allocated by FPL is ALWAYS returned
     when calling FPL's cleanup routine.

   o Multi source file system. Declare and write functions in any number of
     files and call cross-file! FPL keeps track of the files and can be made
     to flush all files not in use.

   o Invoking single, already declared/defined, FPL functions from another
     FPL invoke is intuitive and easy done.

   o Internal functions can be replaced by user functions.

 Package advantages:

   o FPL is freeware! Use it for free.

   o Includes an example program that interprets a common C language expression
     from the command line.

   o More than 190 KB documentation (lots of it in amigaguide format).
