Abstract. Guardol is a domain-specific language designed to facilitate the construction of correct network guards operating over treeshaped data. The Guardol system generates Ada code from Guardol programs and also provides specification and automated verification support. Guard programs and specifications are translated to higher order logic, then deductively transformed to a form suitable for a SMT-style decision procedure for recursive functions over tree-structured data. The result is that difficult properties of Guardol programs can be proved fully automatically.
DASL is a direct descendent of the Guardol Domain-Specific Language for Cross-Domain Systems REF .
