I’m sorry to not having answered. There is now a modified seq in sbase +
manpage[0]. It is based on the seq.c of Kurt but resembles much closer
the format difficulties. For example doing atof() on the arguments won’t
preserve the aligned width in »60.000«.

Have you tried the fmtvalid() function? It seems like there is a typo
where it is used. Such a function would still be useful in the now ex‐
isting seq.c.
