SQLRPG with LIKE

[Damien Spriet <damien.spriet@xxxxxxxxxxxxxxxxxxxx>]

I'm trying to use LIKE in the SELECT on my SQLRPGILE pgm but it doesnt't
work why ? 
If I put equal works well. 

C* 
C *ENTRY PLIST 
C              PARM BIB 10 
C              PARM FIC 10 

C/EXEC SQL 
C+ DECLARE A CURSOR FOR 
C+ SELECT DBXFIL, DBXLIB, DBXATR, DBXTYP, DBXTXT 
C+ FROM QADBXREF 
C+ WHERE DBXATR = 'PF' AND DBXLIB = :BIB AND DBXFIL 
C+ LIKE :FIC 
C/END-EXEC 

C/EXEC SQL 
C+ OPEN A 
C/END-EXEC
