Re: RdLine with variable length field

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

If you increase the length of a VARYING field, for example if the length is 5, and you do %len(field)=10, RPG will automatically blank out the 5 characters it just added.

That's why you have to set the field to it's maximum length beforehand, otherwise RPG will blank out the characters you just received.
