hello everyone, I want to get value of DELT (time step) in fortran, however using CALL DSRVAL('DELT', INDX, RVAL, IERR) has a problem. main purpose is simple, just want to use this function as a record time at certain condition example [The plus-equals operator in python (+=) which provides a convenient way to add a value to an existing variable and assign the new value back to the same variable]

--> i += DELT -->if i > a: ------>certain condition

is there any other way to simulate this condition using FORTRAN?

I believe += is unique for python. In fortran use i = i+DELT.

Dear Dr Perolofl, i tried using DELT function but it seems (DELT is not iterated just a fixed value) is there any Fortran code for time step iteration (example 0.00025, 0.00050, 0.00075)

yes, DELT is the time step for the simulation. Are you using a time step of 0.00025 s? The actual time of the simulation is stored in variable TIME, so TIME is increased with DELT for every time step in the simulation.
