DESL accomplishes each task and/or subtask via the use of a "block" of script as shown in the following general paradigm :

A building block approach, using one or more replications of this type of single block, can result in the construction of a very powerful tool (sequence of DESL script blocks).

The DESL Schematic

So, for example , to go from an Excel tab-delimited ASCII file through a DESL filtering operation, then through a DESL curve fitting operation, then back to an ASCII file (ready for importing into Excel), a DESL process schematic shown by the following could be employed :

Export columns of Excel spreadsheet to tab-delimited ASCII file tab-delimited ASCII file > DESL Translate > new DESL SIF file #1 New DESL SIF file #1 > DESL Filter > new DESL SIF file #2 New DESL SIF file #2 > DESL Fit > new DESL SIF file #3 New DESL SIF file #3 > DESL Translate > tab-delimited ASCII file Import tab-delimited ASCII file into Excel
