Initializing help system before first use

Checking memory usage
Type: Transportation
Rating: 2 (easy-medium)
Description: Model efficiency may be measured in terms of model execution time and memory usage. The latter can be obtained with the help of the lsmods and info commands of the Mosel command line editor as shown by the example flow.mos that demonstrates the use of dynamic arrays to reduce the size of tables.

Check memory usage
==================
Use the following command sequence at the command line:

mosel debug -g flow.mos
lsmods
info COST
quit

Remove the keyword 'dynamic' from the array declarations and perform 
once more the same command sequence.
