==UDDS    UNDER  CONSTRUCTION   MORE  CODE TO BE ADDED SOON ==
The manual that describes the 5250 data stream is 5494 Remote Control Unit, Functions Reference. SC30-3533-04 (topic 15) [http://tn5250.sourceforge.net/resources.html]


The purpose of this program is to demo an example of a program using UDDS.

It shows file data, but is limited to 6048 max rcdlen.  

Use the code below at your own risk, no warranty is expressed or implied or even that the code is functional.


I am also inculding wrapper programs to make the displayer more useful, but there is no 'make' instruction.  I am assuming you know enough about compiling source to figure it out for yourself. Once compiled the command to run it is  'DSPFL  yourlib/yourfile '
