Re: RdLine with variable length field

Hi Jerry,

This works as it is returning the first two bytes of the input_string, but now when testing with variable length data the RdLine hangs until a minimum of 56 bytes are received.

rdline() is supposed to read until it gets a newline character. Perhaps it's not receiving the newline? You can tell it which character signals newline by passing the 5th parameter to rdline()

What I'd like to be able to do define the input_string as say 8192 (8k) and have it be able to accept a variable length input string with fewer (but up to) the 8k limit. So far I haven't seen any lab results that are larger than 5k but I know that pathology reports can be quite large, and then there are the simple tests that are usually less than 1k.

Okay...? Rdline() appears to handle strings up to 32766 chars long, so I don't see why this is a problem?
