可以考虑DelphiWebScript,可以执行delphi语法的程序,我正在用,感觉不错。
免费的,有源码好像vcl.vclxx.com有下载,叫做dws*.zip,也可以到它的网站上下载,网址...(等我查以下)

------------------------------------------------------DESCRIPTION
------------
Expression parser 1.60 is a set of two components - TExprParser and
TEPUserLib, for evaluating expressions at run time.
TARGET ENVIRONMENT
------------------
Delphi 1.0, Delphi 3.0 and Delphi 4.0
FEATURES
---------
Supports using of user-defined variables, function arguments,
all arithmetical and logical operators, build-in functions,
register your own build-in functions, library of user-defined functions
and aliases editable both at design and run time, on event
evaluated variables and functions.
Library also can be loaded and saved in INI file at design and run time.
Supports using of date and boolean constants and functions.
Returns a list of used variables by the given expression and can
set them values before evaluating.
Has functions to perform checking for a valid syntax of the given expression,
using of known variables and functions, and arguments mismatching,
without evaluating the expression with actual arguments and variable values.There is NO 256-bytes LIMIT of the length of the expressions (in Delphi 1.0),
NO LIMIT of complexity, NO LIMIT of function arguments.
No need to re-parse expressions (or library functions) explicitly,
it is done automatically if the conditions on which they are
last parsed are changed.
Supports names and identifiers with characters in a range #192..#255
for some language character sets.
Enhanced error handling.
Full help and demo included.Additionally there is a free Expression builder set of 8 components
which helps you to build custom expression builder dialogs,
to enable the user to enter a syntax valid expressions, checks them,
and stores in a dataset, and solves them later.To learn more about that, look at:
