Hi friends. i'm trying to make fluent reiterating a time step with my udf. i used compiled udf and the following code to do it.

CURRENT_TIME = PREVIOUS_TIME;

N_TIME = N_TIME - 1;

i see that this code is not true and i've got the following error:

"left operand must be l-value"

for both lines. can anyone help me to do this. thanks.

You cannot do that within a UDF.

but, what can i do for doing that?
