Issue/Introduction

Question: 

An IDEAL main program is calling a COBOL sub-program and getting this error:

DB00501E - OPEN ERROR - RETURN CODE 55 (001)

The URT is assembling and linking cleanly with cc=0.       

What can cause this error?

 

Answer: 

The return code 55 indicate a problem exists with the User Requirements Table assembly. Some things that can cause the error are: 

  • Picking up mixed release modules during the assembly of the URT
  • The URT was assembled with a different release CABDMAC macro library
  • Not specifying LE=YES with LE runtime programs 
  • The linkedit should have ENTRY program_name not ENTRY BEGIN
  • Including the wrong URT in the linkedit of the program
