C **IS** a strongly typed language as anyone who tries to pass a pointer to an 
array of 
characters into a function that expects a pointer to char will discover.  Hence 
the 
plethora of C code that contains casts to void to shut the bloody compiler up!

I guess RPG is strongly typed too, just not as much as C.  When prototypes, 
dates, times, 
timestamps, and arithmetic are involved it is very particular.  It's more 
tolerant with 
MOVE since it will try to convert from one type to another sensibly.  C won't 
let you 
assign one type to another unless they are numeric and then it does the type 
conversions 
automatically.  It won't even let you assign the contents of one structure to 
another if 
they have different types.  The best you can do in C to mimic a MOVE is 
memcpy().

Both languages will let you redefine storage to make one data type appear as 
another (a 
DS in RPG, a union in C).

I agree with your comments regarding the compiler.  My problem could be solved 
by the RPG 
compiler.  (Although your discussion of string differences is very much what 
happens with 
the *STRING keyword.)

Simon Coulter.
