Perhaps we are seeing something a little different then.  For me,
the variable width always snaps back to 8.

Oh, wait a second.  If I click on the "type" entry then I can set
the width and decimals in the dialog box that appears, and that
works fine.  It's only a problem if I try to set them by clicking
on their individual fields.

f1 and f2 are used in error messages only, to identify the
columns that the data came from.  I think you are using data_in()
correctly.  It is not well-documented, and I should improve its

But the error message on GET is fairly clear:

         error: corrupt system file: x: String variable A has
                numeric format specifier F.

This implies that the dictionary itself was incorrect and that it
gave a string variable a numeric format specifier.  If `v' is the
"struct variable" then this would be v->type == ALPHA,
v->print.type == FMT_F.  Does this seem possible to you?
