Adding verbs INPUTE and INPUTN: what is verifyoptions?

[Lotes]

There are two additional verbs (besides FILE/XFILE) with priority 1 where the documentation is incomplete: INPUTE and INPUTN

Both verbs have this verify options at the end of the definition, like here:

INPUTN col,row,omask$,imask$,flags$,restore,val{:(verifyoptions)}

But it is not explained in detail and there are even no examples. How would an example with verify options look like?

[StephanWald]

INPUTE (0,ERR=*next) C,R,M$,P$,A$:("end"=3000,LEN=1,5)

This is similar to INPUT, basically telling some rules about how the input should look like or where to jump to on specific inputs.
Valid verifyoptions are explained with the READ verb
