RE: RdLine with variable length field

Scott, I think one could avoid the separate setting of variable length. The
change would involve coding:

%Len(String) = RdLine( cli : %addr(Input_String: *Data):
%size(Input_String) :

Instead of

Len = RdLine( cli : %addr(Input_String: *Data): %len(Input_String) :

But I'd need to research whether the %size() variable should actually be
reduced by the length of the length portion.

Hi Jon,

Seems to me that you still have to set the string to it's maximum
length before calling rdline() and set it back to the correct length
after calling rdline().

So you can't eliminate all that code. The only thing you can do is
change %addr(var)+VARPREF into %addr(var:*data). You can't eliminate
the rest like you suggested.

If using V6R1 (or 6.1 as it is now known) the easiest way to handle
the data portion of a variable length field by address is to code
using %Addr( fieldName: *Data) which will automagically skip the

first

two or four bytes as appropriate. So these:two lines

%len(Input_String) = %size(Input_String)-VARPREF (VAPREF is 2)


Len = RdLine( cli : %addr(Input_String) + VARPREF :
%len(Input_String) :
*On );

Can be simplified to one - and of course the constant VARPREF is not
required either.

Len = RdLine( cli : %addr(Input_String: *Data): %len(Input_String) :
