MCOPY
[MRTCAL\]MCOPY [IN|CURRENT] /FILE IndexFile
Copy the named index (default current) from memory to the given file to
disk. Any pre-existing file is overwritten, except that you can not
overwrite one of the input index files involved during this operation.
This command is useful for a few main purposes:
- extract a subset from an index file, by combining the commands INDEX
OPEN, MFIND (with criteria), and MCOPY,
- merge several index files, by combining INDEX OPEN, INDEX APPEND
(repeated), MFIND, MCOPY,
- convert an old format file to latest format, simply by using INDEX
OPEN, MCOPY IN.
