ABSTRACT
We report on an implementation of a pascal translator that generates code for mobile software messengers (agents): these agents can roam a network of interconnected execution platforms on behalf of a user, enabling users to implement customized network functionality themselves. In this report we focus on the language extensions (pascal-m) and the implementation aspects of the translator. The main departure in pascal-m from standard pascal is that the programmer has access to the generated code in form of string constants. An interesting aspect of the "pascal-to-MØ" (ptom) translator is that pascal-m is translated to the stack-based high-level language MØ. MØ is similar to postscript and has no notion of memory addresses although pascal compilers usually produce code for machines or software interpreters with word addressable memory: because MØ completely hides the exact memory locations of code as well as data, we have to use other implementation approaches for activation frames, var...
