SPL

I call the RUNSQLSTM and the SPL drops the procedure but fails to create the
SPL because there is some syntax problem.  
The next time I run RUNSQLSTM I have to comment out the --DROP.  
 
Is there a way to condition the drop statement in a stored procedure?  
 
Thank you for any help with this.
