XPL brings the dramatic extension of high-level language power to these developers, as well as to EXPO, a product with many thousands of users worldwide. The use of XPL as an adjunct to EXPO gives EXPO developers even more horsepower without giving up any of the powerful, built-in features which make EXPO so popular. The XPL language workspace manages numerical data at a high level as unlimited-length virtual arrays. From then on, DOW is available to XPL as a continuously growing series of values.
Hot variables can be arrays, time series, matrices, or scalars.
XPL scalar hot variables can be thought of as being like a single cell in a spreadsheet. Unlike other high-level languages, XPL was designed for high performance with time series data and uses a syntax which is very familiar to most programmers. The value of XPL's syntactic similarity to C cannot be overemphasized. XPL also supports both global and local variables. XPL Testing XPL has been in use internally at LMT and at select test clients for over six months.
