st: How to replace .docx file?

[Friedrich Huebler <fhuebler@gmail.com>]

I am experimenting with the creation of .docx files and don't know how
to specify the -replace- option. According to -help mf__docx-,
documents are saved with this command:

_docx_save(dh, string scalar filename [, real scalar replace])

Take this example, adapted from -help mf__docx-.

* Create a document
mata:
dh = _docx_new()
end

* Add some text
mata:
_docx_paragraph_new(dh, "Some text")
end

* Save file
mata:
res = _docx_save(dh, "example.docx")
end

* Replace file
mata:
res = _docx_save(dh, "example.docx", replace)
end

The last command results in an error message.

. * Replace file
. mata:
------------------------------------------------- mata (type end to
exit) --------------------------------------
: res = _docx_save(dh, "example.docx", replace)
                 <istmt>:  3499  replace not found
(0 lines skipped)
----------------------------------------------------------------------------------------------------------------
r(3499);

I tried different variations of the -replace- option with the same
result. What am I doing wrong?
