Here's an example of CVTEFN (using RPG calling the MI function, not an
MI program).  Indeed it seems a bit more than twice as fast as my routine.
Even if I wrap CVTEFN in my own procedure, so it has a convenient
"x = cvtnum (string)" interface, it's still almost twice as fast.

My routine allows for more flexibility in the strings though (allowing
parentheses to indicate negative, for example), and allowing either
commas or blanks as separators.

D cvtefn          pr                  extproc('_CVTEFN')
D    rcvr                         *   value
D    rcvrAttrs                        like(attrs) const
D    source                     40a   const
D    sourceLen                  10u 0 const
D    mask                        3a   const

D PACKED          c                   x'03'

D attrs           ds
D    type                        1a   inz(PACKED)
D    length                      5u 0
D      decPos                    1a   overlay(length : 1) inz(x'09')
D      digits                    1a   overlay(length : 2) inz(x'1E')
D    reserved                   10i 0 inz(0)

C                   callp     cvtefn (%addr(num)
C                                   : attrs
C                                   : string
C                                   : %len(string)
C                                   : '$,.')
