One of the core activities in OpenGrADS is the development of high performance user defined commands and functions. The classic user defined functions (UDFs) in GrADS relies on disk files for the transmission of data to and from the UDF. While this approach is somewhat robust and language independent, reading the exchange file is somewhat tedious and the unnecessary I/O leads to a large performance penalty.
