File: _find_cd.p

Description:
   This routine finds particular code blocks and returns there recid.
   This is implemented as a seperate .p
   
   Associated _code-text records are also deleted.

Input Parameters:
   p_Proc-id - Recid of the procedure file
   p_case    - The case we are looking for. 
   p_subcase - The subcase (of the case) we are looking for. 
     This file finds the:
      FIRST - first code block (p_subcase ignored)
      LAST  - last code block  (p_subcase ignored)     

Output Parameters:
   p_Code-id -  Recid of _code found (or ? if none exist).
