Yes, Vice doesn't support writing .TAP files. At least according to their instruction manual, and what I have found in practice:
section 5.5 of VICE manual paragraph 4:
Supported formats are D64 and X64 for disk images (devices 8, 9 and 10) and T64 for tape images. Notice that T64 support is read-only, and that the cassette is automatically rewound when you reach its end.
I noted that the rewind part is not actually the case, it just stops at the end of the image, but the counter stays, and sometimes the rewind button doesn't even work, so you have to reattach the tape image. I also noted that there are many more formats available on VICE than this manual specifies. It may indeed be that their own manual is blatantly false and undersells the capability of an entire drive mechanism, but that would be nuts.
As the saying goes: if you've seen one Forth then, well, you've seen one Forth.
LOL ain't that the truth! FORTH and COMAL...
Comal actually has sections in it where it tells you that you'll have to change syntax to use comal software with comal...ON THE SAME SYSTEM!! LOL. They actually changed regular syntactical conventions in a subsequent version, and then just sent a paper addendum to tell users why all the software(what little there was) would have to be combed over painstakingly to find all the = that needed to be := or whatever for some bizarre reason they didn't explain. I guess that, and the fact it cost 130$ in 1980's money kind of put people off(as well as a scathing article from a magazine accusing them of fraud). I still like COMAL 80...and actually did pay 130$ in 2010s money to get the cartridge 3 years ago...originals aren't easy to come by, and with the above shortcomings long over, it is very easy to build presentable modular applications quickly in comal.
