 From the value you assigned to it.  If you have something like "r = xx"
and xx is a (1,.0) field, then r is now a (1,.0) field.

I assume the zero came from a (1,.0) field, and not a literal "0"?

Try the following:

::end:
@entsel::show "\{T}-test assign to uncast field":
::end:
@keyt::xx:
::xx = "foo" ; gosub showit:
::xx = @t4 ; gosub showit:
::xx = "1"/"2" ; gosub showit:
::end:
showit::mesgbox "'" & xx & "'\n(" { @len(xx) { "," { @edit(xx) { ")":
::return:
