of an argument string is restricted.
MPE/iX NOTES
The current MPE/iX implementation of make does not understand the format of libraries. As a
result, it is ubable to extract the date/time stamp for an archive and thus, cannot compare that
date/time stamp to those of other files.
For more information on how the current MPE/iX implementation may affect the operation of
this utility, see Appendix A, MPE/iX Implementation Considerations.
