There is already C code in DCL, albeit in the minority (< 10%).  We have discussed conversion of large portions of Macro-32 code into C code in DCL (think symbol table management and the like).  The code that manages stack context, etc. needs to stay in Macro-32 (and even some target assembly) due to DCL's unique ability for "^Y", do a set of DCL commands, "CONTINUE".  And yes, we have discussed modifying that for images installed with privs.
