DCL Compiler?

» close window

The Question is:

 
Does a compiler for DCL exist? If so what is the performance gain?
Thanks
 
 

The Answer is :

 
  Interpreted languages do not always compile particularly well, and the
  syntax and the syntactic capabilities of DCL in particular do not lend
  to an easy compilation (or to a full implementation of DCL) -- the
  substitution capabilities in particular make the creation of a full
  DCL compiler very difficult.
 
  The OpenVMS Wizard has heard of a few DCL compilers over the past
  decades, but has not worked with one -- if you cannot afford the
  level of overhead of DCL (and there are ways to reduce the overhead
  of DCL processing such as the DCLDIET tool used within OpenVMS
  Engineering), the usual approach involves executable images and other
  languages.  (C or Perl, for instance...)
