It is a base calumny and deserves to be beat some more.

Here is an example using RPG III:
PARMC
PGM                               
DCL &DECIMAL *DEC (3 0) VALUE(1)  
CALL PARMR &DECIMAL               
ENDPGM                            

PARMR
     C           *ENTRY    PLIST                         
     C                     PARM           NUMBER  30     
     C                     ADD  1         NUMBER         
     C           NUMBER    DSPLY                         
     C                     SETON                     LR  

It doesn't use a display file, but it will work just the same if the CL had
a DSPF.  It also works the same using RPG IV.  Numeric variables will be
passed properly.  I have been using these examples from the S/38 days.  I
wish I didn't have to.  

Here's a rhetorical question: Why would an advanced architecture like the
S/38 (now AS/400) have features like hardware tag bits yet not allow
programs to pass numbers back and forth?
