> I have a new RPGLE application that gets its parameters from

>
> Parm Members Type( *char ) Len( 10 ) Max( 8 )
> Parm MembrTypes Type( *char ) Len( 10 ) Max( 8 )
> Parm Libraries Type( *char ) Len( 10 ) Max( 8 )
> Parm OmitMTypes Type( *char ) Len( 10 ) Max( 8 )
>
> By virtue of the MAX (Maximum values allowed) parameter, set
> at eight, the
> value issued to the CPP is a structure, starting with a 2-byte binary
> number-of-values, followed by the values themselves. The
