If you want my take on this, the problem is in line 44 of zipfile.ado which
reads


*************
gettoken comma   0 : 0
*************

and probably needs a " , parse(", ")":

-gettoken- normally identifies tokens by watching out for blanks, as its
help file indicates. If, in your call to -zipfile-, you do not provide it
with a blank after the comma separating the zipfilename from its options, it
cannot tell that -replace- has been specified, and stashes -replace- into
the "comma" macro. The line 45 " gettoken replace 0 : 0" never gets a chance
to do its magic as "comma" has already eaten its lunch. The subsequent -if-s
then -somewhat correctly- identify a problem with the -saving- option when
really the problem lies in the parsing...

I used -zipfile- for the first time and obtained an error with the
first syntax. Stata usually lets one use "save,replace" even if the
file does not exist. So the behavior below was unexpected and kind of
a nuisance. And it is contrary to the help file.

. zipfile eq5d2.dta, saving(eq5d2,replace)
option saving() misspecified
r(198);

. zipfile eq5d2.dta, saving(eq5d2)
    adding: eq5d2.dta
successfully zipped eq5d2.zip
