automatic wait!!!

hi
I ve a program YSETLIB which runs during a batch

CALL YSETLIB PARM(' ')                                
               
I get the following error if the file SFE.PARM (which
iam using)comes lately from other programs....
-------
   400 - RTVOBJD OBJ(SFE.PARM) OBJTYPE(*FILE)
RTNLIB(&FLIB)            
File SFE.PARM in library *LIBL not found.             
                
Function check. CPF9812 unmonitored by YSETLIB at
statement 400,      
  instruction X'000F'.                                
                
CPF9812 received by YSETLIB at 400. (C D I R)         
               
------
when the above error comes i wait for some time and
check for the file and retry then it works..now it has
become head ache to see this error again as the file
is coming lately for most of the times...

is there some way i can make my program YSETLIB
automatic wait and retry every 30 seconds?
Thanks so much for your help in advance..
Murali.
