This code compiles fine with C11.0 but fails to compile with C11.1:

```clarion
  PROGRAM

Class1 CLASS,TYPE
Function1 PROCEDURE,STRING
                    END

  MAP 
Function1 PROCEDURE,STRING
  END
  
  CODE
  
  BIND('Function1',Function1)    
  
Class1.Function1 PROCEDURE!,STRING
  CODE  
  RETURN ''
    
Function1 PROCEDURE!,STRING
  CODE  
  RETURN ''

```

The error is: `Parameter type label ambiguous (CODE or DATA) - Test.clw:13,20`

Probably it's related to this fix in [Build 11.1.13744](https://clarionhub.com/t/new-blog-entry-on-clarion-11-1-13744/4210): `FIX: Compiler: incorrect code could be generated for a BIND statement`.

The obvious solution is to rename one or the other function, but as both are widely used in a relatively large code base (`Function1` is a bindable stub used in FRB reports to call the class function), I wonder if anyone had this problem before and found a simpler workaround.

This is a minimal test project: [BindProcMethod.zip](https://clarionhub.com/uploads/short-url/txYauxp4eDNDchoQNHjieji1zqW.zip) (1.2 KB)

A workaround is to create another stub in a local `MAP` just to let `BIND` work

```clarion

  BIND('Function1',locFunction1)    
  ...

locFunction1 PROCEDURE!,STRING
  CODE  
  RETURN Function1()

```

</div>

Another workaround is to use a reference to a procedure

```clarion
  PROGRAM

Class1 CLASS,TYPE
Function1 PROCEDURE,STRING
                    END

  MAP 
Function1 PROCEDURE,STRING
Function1Type PROCEDURE,STRING,TYPE
  END

refFunction1 &Function1Type
  
  CODE
  
  refFunction1 &= Function1  
  BIND('Function1',refFunction1)    
  MESSAGE(EVALUATE('Function1()'))

Function1 PROCEDURE!,STRING
cl1 Class1
  CODE  
  RETURN cl1.Function1()

Class1.Function1 PROCEDURE!,STRING
  CODE  
  RETURN '123'

```

I can only confirm that I see the same problem you are experiencing

I appreciate this answer as it may answers a similar question I had about how to assign a function to a class and execute it later on within a method. I will play around with your sample. Thanks.

I reported this ([43441](http://problemtracker.softvelocity.com/UpdtAllBugsview.php?ID1=43441)) and now has status _Bug confirmed_.

One more reason to delay C12 for a half of year.
