JOINKEYS to combine two files

I would like to explain my scenario using sample code below,

Two files need to be joined by means of acct# using JOINKEYS but in file1 acct# exists at position:33 but in file2 acct# exists either at position:1 or 2 depends on char 'C' at position:1. In other words if char 'C' exists at position:1 then we need to consider acct# from position:2 otherwise consider acct# from position:1. I want do all these things in a SINGLE step.

Hope i made my requirement clear. Appreciate your solution.

I think this is what you want (notice the JNF2CNTL in-stream):

//STEP010  EXEC PGM=SORT,                      
//             REGION=0M                    
//SYSPRINT DD  SYSOUT=*                        
//SYSLIST  DD  SYSOUT=*                        
//SYSTOTAL DD  SYSOUT=*                        
//SYSOUT   DD  SYSOUT=*                        
//*                                            
//SORTIN   DD  DUMMY
