- ===============
-
- 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 and variables that
- FPL should accept. The library will call a function in the software whenever
- any of these functions are used or variables are read 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, sprintf and the FPL specific substr, eval,
- ltostr and interpret!
-
- o Supports the preprocessor instruction "#line" enabling FPL to run
- common C preprocessor output.
-
- o Some variable reference/pointer support like that C has!
-
- 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 around 45KB (amiga version)/65KB (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.
-
- o Runs on AmigaDOS 1.3 and later.
-
- 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 ~200 KB documentation in amigaguide format (+ clean ASCII versions)
-
- FPL is Copyright (C) 1992-1995 by FrexxWare and freely distributable for
- NON-COMMERCIAL PURPOSES ONLY, including extensive documentation and source
- code.
