HTTP Post with dynamic values

This is the first time that I've used Rebol and I am having a problem with what is probably a simple syntax issue. I need to post form variables to a page and read the resulting page back into a variable for further processing. The form variables contain dynamic elements. I see how I can use rejoin to combine the dynamic elements into the string but I don't know how to then pass that resultant string to read/custom. The command that I need to execute is: read/custom http://www.example.com/GCA00P00/WIQ1/WINQ120[ post M12_SEL_DINI=89T4810&K01=WINQ120&K02=89T4810&K03=&K04=&K05=0&K06=&DFH_STATE _TOKEN=abokyfjg&DFH_MAP_STATE_TOKEN ] where the values for the first and third parameters need to be inserted through variable substitution. After processing, the resultant filename should also be this variable + ".txt" Can I create a string with rejoin and pass that string to read/custom? Is there some other approach that I should take? Many thanks in advance. Marc Stein
