Universal string expression compilation runtime library FORCAL

Usually, programs designed using various high-level languages such as C/C++, VB, delphi, FORTRAN, etc. cannot dynamically compile the source code. Forcal can add the function of dynamic compilation of string source code to all these applications. Forcal can be used in the design of various mathematical software, and can also be used as scripts for report processing, web, configuration software, games, etc., with high execution efficiency.

Forcal32W.dll is the 32-bit Unicode version of Forcal. It is a dynamic library that compiles and calculates Unicode character expressions. The operators that can be used in expressions are +, -, *, /, ^, >, >=, <, <=, ==, ! =,&,|,! , ++, --, etc., Forcal has many programmable functions such as numerical calculations, logical operations, relational operations, character data processing, process control, function calls, etc.

Forcal supports Chinese programming and can use Chinese identifiers, such as Chinese function names, Chinese variables, etc.

Forcal uses key trees to save and retrieve data information. You can use Forcal to save and retrieve any type of data. It has high storage efficiency and high search efficiency.

Forcal has many built-in basic functions (first-level functions and second-level functions), but you can use (C/C++), Delphi, FORTRAN and other compilers to easily expand these basic functions (second-level functions), and you can make these functions complete extraordinary functions.

Forcal supports three types of expressions: integers, real numbers, and complex numbers. You can use these expressions to design custom functions in Forcal.

When Forcal calls extended or customized functions, it is the same as calling system built-in functions. There is no difference.

Forcal supports recursive calls for all functions, whether they are built-in, extended, or customized.

When calling a function, Forcal supports both call-by-value and call-by-address (call by reference). When the latter method is used, more values ​​can be returned from the function.

Forcal optimizes the code as much as possible, so the running speed is also very good. The calculation speed of the first-level function is about 50% of the speed of (C/C++) or FORTRAN, and the speed of the second-level function is slightly reduced.

The Forcal compilation system supports modular compilation, which is very helpful for designing complex software projects.

The Forcal compilation system can accurately locate the location of errors during compilation, making it very convenient to eliminate errors.

Forcal uses the Win32 standard function calling method (stdcall calling protocol) to output dynamic library functions, which can be used by C/C++, VB, delphi, FORTRAN and other programs.

It is easy to extend the function of Forcal. There is only one output function FcDll32W (...) in the Forcal extended dynamic library, which is very convenient to design and apply. Forcal extended dynamic libraries can be designed in C/C++, delphi, FORTRAN and other languages.

Although Forcal32W.dll only supports 32-bit programs, Forcal code written on a 32-bit platform can run on a 64-bit platform without modification.
