Numbers and text a user can edit in Igor Pro

SetVariable binds a control to a global, so the value outlives the click.

Function AddFields()
    NVAR threshold = root:Settings:gThreshold
    SVAR label = root:Settings:gLastFile

    SetVariable thrSet, pos={16, 80}, size={200, 18}, bodyWidth=70
    SetVariable thrSet, title="Threshold", value=threshold
    SetVariable thrSet, limits={0, 10, 0.1}, proc=ThresholdChanged

    SetVariable nameSet, pos={16, 104}, size={280, 18}
    SetVariable nameSet, title="File", value=label
End

How it works

1. value= names the global the control reads and writes.
2. limits={low, high, step} bounds it and sets the arrow increment.
3. bodyWidth= keeps the box a sensible width next to a long title.
