Using the debugger and profiler Description The Mosel debugger and profiler may be used either through Xpress Workbench or from the Mosel command line. The model prime2.mos shows typical debugging and profiling command sequences. The model prime3.mos is a more efficient re-formulation of the same algorithm. The model runprime2d.mos shows a debugging command sequence for a submodel started from this model.

Debugging
=========
Use the following command sequence in the Mosel command line:
mosel debug prime2.mos 'LIMIT=50'
break 31
bcond 1-1 getsize(SNumbers) < 10
cont
print n
display SNumbers
display SPrime
cont
quit
Profiling
=========
Use the following command in the Mosel command line:
mosel profile prime2.mos 'LIMIT=50'
Obtain information about memory usage:
mosel debug prime2.mos
info SPrime
lsmods
quit
