If you are referring to the rdline() routine from the socket tutorial (I guess that's what you're referring to... took me about 30 mins to figure that out... I wrote that routine 12 years ago, and have scarcely looked at it since.) then, no, it does not work with VARYING fields. At least not *directly*.

You could make it work by doing something like this:


%len(Input_String) = %size(Input_String) - VARPREF;
len = RdLine( cli
: %addr(Input_String) + VARPREF
: %len(Input_String)
: *On );
if (len < 1);
%len(Input_String) = 0;
%len(Input_String) = len;

All this does is set the length of the input_string to it's maximum length, then get the address of the data portion of the VARYING field (by adding 2 to the start, skipping the length bytes). Then when it's done, setting the length to the proper length for what was received.

Cumbersome, yes... but you can package it into a subprocedure called "rdlinev" or something, so you only have to code it once.

Though, personally, I'd suggest eliminating rdline as it's extremely inefficient.

I have the following code in which I encounter two problems. First when viewing the Input_String variable in debug, only the last 54 bytes are shown - the first two are truncated. (The string sent contains 56 bytes). The debugger monitor says the field is 56 bytes, as does the dump listing. Second the "If %Len(Input_String) < 1 Or %Len(Input_String) > 56;" triggers an RNX0115 (Length of varying length variable is out of range). Does Rdline not work with a variable length field? (The RdLine code is from Scott Klements tutorial.)

D Input_String S 56A Varying
If RdLine(cli: %addr(Input_String):56:*On) < 0;
Callp Die('Error calling RdLine()');
Callp close(cli);

If %Len(Input_String) < 1 Or %Len(Input_String) > 56;
Error = Yes;
Return_String = %Trim(Return_String) + Error00;
