Write a simple API extension for MetaStock

Using one of the Metastock Development Kit resources - External Function API, I need to build a few utility functions (external to Metastock native environment) which would be written in a lower level programming language (C, C++, Pascal or PowerBasic). Some of the features of the MetaStock External Functions (MSX) API are: -Create MetaStock Custom Formula functions in a Win 32 DLL -Use the power of conventional programming languages -Sample code provided for C, C++, Pascal, and PowerBASIC -Unlimited number of functions per DLL -Argument types include Data Array, Numeric, String, and Custom -Up to 9 arguments per function Utilities I am interested in at the moment are: - write output to a comma delimited text file (akin to WrineLine() in C#); - provide ability for string concatenation function and string formatting.
