Indicates what should happen if chunking is detected MEMCHECK
0 - A warning is issued but makemap then continues to produce a map from the chunked data.
1 - An error is reported with status SMF__NOMEM and no map is created. The output map is created as normal if the available memory is sufficient to avoid chunking.
2 - An error is reported with status SMF__NOMEM and no map is created. In addition, an error is also reported with status SMF__MEMCHK and no output map is created if the available memory is sufficient to avoid chunking. Thus if memcheck is 2, no map is ever created. This is intended as a means to check whether chunking would or would not be used if makemap was to be used subsequently to create a map.
Note, in either case the SMF__NOMEM error is reported only if chunking is caused by lack of memory, not if it is caused by the supplied data being discontiguous. [0]
