Using the Mosel Command Line

The Mosel Command Line is supported on all platforms that Mosel can be run on.

Standard sequence for model execution from the command line:

mosel exec mymodel.mos            Execute (=compile/load/run) model 'mymodel.mos'
mosel mymodel                     Short form (works with 'mymodel.mos' or 'mymodel.bim')

Some useful commands (see `Mosel Language Reference manual' for the full list):

Command line help text:

mosel -h

Mosel version:

mosel -V

Display functionality:

mosel exam[ine] [-cspthirvaum]

Execute a model file:

mosel exec[ute]

Compile a model file:

mosel comp[ile] mymodel.mos

Load and run a BIM file:

mosel run mymodel.bim

Start the debugger:

mosel debug mymodel.mos

Run the profiler:

mosel prof[ile] mymodel.mos

Perfom a code coverage run:

mosel cover[age] mymodel.mos

List available modules/packages:

mosel lslib

Examples:

mosel comp mymodel.mos -o mybim.bim   Compile to a specified BIM file name/location
mosel prof mymodel.mos            Perform a profiler run (output in 'mymodel.mos.prof')
mosel exam -h                     Display Mosel version info and paths
mosel exam -a mybim.bim           Display annotations of a model or package
mosel exam -ps mmxprs             Display parameters and subroutines of module 'mmxprs'

Setting model runtime parameters:

mosel exec mymodel NT=5 DATAFILE="mynewdata.dat"    Source in mymodel.mos
mosel run mymodel NT=5 DATAFILE="mynewdata.dat"     Loads mymodel.bim
mosel mymodel NT=5 DATAFILE="mynewdata.dat"         With mymodel.mos or mymodel.bim

Debugger commands

Breakpoints:

break  delete  bcond[ition] breakpoints breaksub

Model execution:

cont  next  step  finish  model

Output:

display undisplay list print info exportprob
lsattr lslibs lslocal lsmods lssymb

Stack access:

up  down  where

Interpreter options:

option

Termination:

quit

Example: Simple debugging sequence

mosel debug debugexpl.mos         Start Mosel debugger
break 20                          Set breakpoint at line 20
cont                              Execute up to the breakpoint
print D                           Print out symbol 'D'
cont                              Continue model execution
info Arr                          Information about model object 'Arr' (e.g. size)
lsmods                            Display model info (e.g. memory usage)
quit                              Quit the debugger

Example: Debugging a submodel

mosel debug debugmaster.mos       Start Mosel debugger
breaksub 1                        Stop at start of submodels
cont                              Execute up to the breakpoint
break 25 debugsub.mos             Set breakpoint in the submodel
display SNumbers                  Display watch on object 'SNumbers'
cont                              Execute up to the breakpoint
break 31 debugsub.mos             Another submodel breakpoint
bcond 2-2 SNumbers.size < 10      Condition on 2nd submodel breakpoint
cont                              Execute up to the breakpoint 2-2
quit                              Quit the debugger
