how to use ord for an uncontrolled set (allias set)
how to use ord for an uncontrolled set (allias set)
hi,
for example look at this:
set i /1*10/
allias (i,k)
eq(i)$(ord(i) ne ord(k))..etc
while compiling, i get this error "Uncontrolled set entered as constant"
any suggestions on how i can fix it?
thanks

RE: how to use ord for an uncontrolled set (allias set)
Hi Reza
It is not clear what you want to achieve as you don't show the complete equation.
If you use ord(i) ne ord(k) like you do, i and k should be part of the equation declaration (like eq(i,k)).
eq(i,k)$(ord(i) ne ord(k)) will drop all the equations with i equal to k.
Perhaps you should send more information on what you want to achieve.
Cheers
Renger

Dear Renger,
Thanks for your kind reply. i did the trick with changing the equation so that it includes the minus value of sentences when i=k.
Best wishes,
Reza.
