1. Invoke SPSM
2. User Dialogue
3. Simulation
4. Generate Outputs
Brief descriptions of these steps are given below.
1. The SPSM is contained in an executable file called spsm.exe in the \spsm\win32
directory. The SPSM is started, or invoked, by typing SPSM followed by a
carriage return (enter) in response to an MS-DOS prompt.
2. The user dialogue session is the first step in an SPSM program run. It provides
an interactive method for changing and examining parameter file contents. The
dialogue proceeds in three stages that correspond to the three types of
parameter files. Control parameters are edited first, followed by database
adjustment parameters, and finally by tax/transfer parameters.
3. Once the user dialogue is complete and a full set of parameters has been
provided, the user no longer interacts with the program and the simulation phase
begins. In this phase the database is read, records are screened, and
tax/transfer calculations are made based on the specified parameter settings.
4. When the simulation is complete SPSM generates the specified output files.
SPSM results are always written to files rather than being displayed directly on
the screen.
EXAMPLE SIMULATION
We are now ready to try the first simulation. The complete dialogue for producing
the program run is given below. Inputs that the user typed have been shown in bold
followed by the ENTER key. Lines are numbered in square brackets for reference in
the text. If you are unsure whether the MS-DOS environment variables are set
correctly just type the following three lines in response to the MS-DOS prompt
(where c: refers to the disk drive where the SPSD/M resides).
