proposal for class STRING

Refine feature substring



  1. Make the specification rigorous.
  2. Weaken the precondition to allow end_index to be one less than start_index, in which case an empty STRING is returned.


An ELKS 1995-compatible version of substring is implemented by every vendor. ISE appears to be the only vendor already compatible with the weaker precondition of this proposal.

Impact of proposed change



The proposal was accepted into the ELKS 2000 draft on 19 November 1999.
