%0Computer Program %TAprepro - Algebraic Preprocessor %XAprepro is an algebraic preprocessor that reads a file containing both general text and algebraic, string, or conditional expressions. It interprets the expressions and outputs them to the output file along with the general text. Aprepro contains several mathematical functions, string functions, and flow control constructs. In addition, functions are included that, with some additional files, implement a units conversion system and a material database lookup system. %ASjaardema, Gregory %Rhttps://doi.org/10.11578/dc.20171025.1039 %Uhttps://www.osti.gov/doecode/biblio/460 %CUnited States %D2011 %GEnglish %2USDOE %1AC04-94AL85000 2011-02-07
