     Ooh!  Now I have to make it sound like I know what I am talking about 
     . . .  Could it be that the Net.data macro is the piece of the puzzle 
     you are missing?  I actually played around with this stuff until it 
     worked.  So I will try to show my simple example.  I am RPG ignorant, 
     however.  I wrote my program in ILE C instead.
     
     
     First of all, I have a link on a web page, which looks like this:
     
     http://hdl/cgi-bin/db2www/web/macros/dril1/cmd1?WBS1=01&WLEV=2&TOC=999 
     99&TLEV=1&DWN=W
     
     
     My Net.data macro, which is named 'dril1', looks like this:
     
     
     %FUNCTION(DTW_SYSTEM) sys1 (IN WBS1, IN WLEV, IN TOC, IN TLEV, IN DWN) 
     {
           %EXEC {
              /QSYS.LIB/C40020.LIB/TEST6.PGM
           %}
         %}  
     
         %HTML(cmd1) {
         <P>     
         @sys1(WBS1, WLEV, TOC, TLEV, DWN)  
         %}
     
     
     The macro runs the C program TEST6 in the library C40020.  Finally, the 
     program contains the following pertinent statements, which pick up the 
     environment variables WLEV and TLEV:
     
     
     #include <qp0z1170.h> 
     
                                           
     int main(void) {                       
          
         
     char *wlev;         
     char *tlev;         
                         
      wlev = getenv("WLEV");                          
      tlev = getenv("TLEV");                          
                                           
     .
     .
     .
     
     
     
     
     I hope this helps.  Please let me know if I need to clarify something.
