## Command Line Interface

All other APMonitor interfaces are wrappers for the command line interface. A problem is executed from the command line interface with parameters that follow the APMonitor executable name.

apmonitor *model_name* {*-flags*}

The optional flags are listed below. The command line parameters are converted to upper-case letters automatically so lower-case parameters are also acceptable. This list of flags can also be obtained by including a non-existant flag, such as *-help*.

-P = generate sparsity.unt (dummy file) -UNLC_COLDSTART (-COLD)= coldstart flag -SPECS = read specs from restart file -UNLC_SKIPREAD = skip DBS file read -UNLC_SKIPWRITE = skip DBS file write -UNLC_SKIPREADWRITE = skip DBS file read and write -UNLC_SSTATE (-SS) = steady state mode -UNLC_SSTATE_MPU (-SS_EST) = steady state MPU mode -UNLC_SSTATE_CTL (-SS_CTL) = steady state control mode -UNLC_ONLINE_SIM (-SIM) = on-line simulation mode -UNLC_ONLINE_EST (-EST) = on-line estimation mode -UNLC_ONLINE_CTL (-CTL) = on-line control mode
