Call or Bound Call

[Buzz Fenner <bfenner@xxxxxxxxxxxxxxxx>]

Hi all,

I'm slowly teaching myself ILE RPG (yikes!), rather RPG IV (apology to 
B.C.).  The following code is a simple call to the command parser.  Here's 
the old code and the new code:

0353.00      C           *IN06     IFEQ '1'
0354.00      C                     CALL 'QCAEXEC'
0355.00      C                     PARM 'DSPMSG'  CMD     6
0356.00      C                     PARM 6         LENGTH 155
0357.00      C                     ELSE


0059.00 D*
0060.00 DRunCmd           pr                  extpgm('QCMDEXC')
0061.00 D command                       80a   const
0062.00 D length                        15p 5 const
0063.00 D*

bunch of code, etc.

0231.00 C*
0232.00 C     *in06         ifeq      *on
0233.00 C                   callp     RunCmd('DSPMSG':6)
0234.00 C                   else

>From a technical viewpoint, are these two chuncks of code equivalent?  Or, 
is the RPG IV code a bound call of some sort?  The discussion in the 
reference manual leads me to believe that the RPG IV code represents a 
dynamic call to QCAEXEC.  Plus, if they are equivalent, what is the 
advantage of the RPG IV code (if any)?
