Use EXTPROC instead.

It certainly is possible to use CLLE procedures from RPG IV but not in an 
expression because CL has no support for return values.  

You must create the CLLE as a *MODULE object and either turn it into a *SRVPGM 
or bind it by copy to the RPG program.  Here is a bind-by-copy example:

<========== CLLE source TESTRPGCLC ==================>
             PGM        PARM(&INPUT &OUTPUT)                   
                                                               
             DCL        VAR(&INPUT) TYPE(*CHAR) LEN(10)        
             DCL        VAR(&OUTPUT) TYPE(*CHAR) LEN(10)       
                                                               
             CHGVAR     VAR(&OUTPUT) VALUE('Got it!')          
                                                               
             RETURN                                            
             ENDPGM                                            

<========== RPGLE source TESTRPGCLR ==================>
     D doStuff         PR            10    EXTPROC('TESTRPGCLC')         
     D   input                       10    CONST                         
     D   output                      10                                  
                                                                         
     D data            S             10                                  
                                                                         
     C                   CALLP     doStuff('Some text' : data)           
     C     data          DSPLY                                           
     C                   SETON                                        LR 
     C                   RETURN                                          


CRTCLMOD   MODULE(SHC/TESTRPGCLC) SRCFILE(SHC/TEMP) SRCMBR (TESTRPGCLC)   
CRTRPGMOD   MODULE(SHC/TESTRPGCLR) SRCFILE(SHC/TEMP) SRCMBR(TESTRPGCLR)
CRTPGM PGM(SHC/TESTRPGCL) MODULE(TESTRPGCLR TESTRPGCLC)                   

then CALL TESTRPGCL
