Yes, because that's not what you do.
[tt]INDEX ON nombre TAG yourtag[/tt] does create a tag "yourtag" inside peps2019.cdx (or however the table is named) and not a peps2019.idx file.
And you don't activate that index with SET INDEX To some file, that is the command to use with IDX indexes.
Once you created an index tag in the CDX you either [tt]USE ahorro!peps201 ORDER TAG yourtag[/tt] or you [tt]SET ORDER TO TAG yourtag[/tt] after you opened and selected the DBF or to switch between index tags.
You shouldn't use IDX index files for normal use, as these indexes only update together with DBF/FPT file changes when they are actively set, CDX files get updated even if you don't SET ORDER.
You may have a problem with 200 char field, as index TAGS are limited to 240 bytes, which in any collation but MACHINE is only 120 double-byte characters. But indexing in MACHINE collation is recommended to make the most use of indexes for Rushmore anyway, especially as that's the collation to use for any non-character data type anyway.
