Remark on the Compiler

We are at release V5R3M0. and have just encountered a bug which may be
of interest.

 

We have global variable defined 

 

D work_ind          s              1A        inz 

D false             c                        '0'

 

In a sub procedure we have 

 

D work_ind          c                        'XX'

 

In the same sub procedure with the value of the global work_ind set to
'0' (false) 

 

The following test fails      

 

If work_ind = false ;

     Do something 

Endif ;                  

 

After giving the constant a unique name (work_ind_xx) the programme
worked fine. 

 

 The constant was being used in place of the global variable.

 

I would have thought that the compiler would have highlighted this as a
warning although I admit we should rethink our standards.
