Writeable variable outside function

[polarkac]

Is there a way to modify a variable that was defined outside a function? Its not that important but it could be useful in some cases. Or maybe I approach this in a wrong way.

For example:

#let total_hours = 0
#let work(hours) = {
    total_hours = total_hours + hours
    [#hours hours]
}

#table(
    columns: (auto, 1fr, auto),
    inset: 5pt,
    [*Name*], [*Desc*], [*Time*],
    "Work 1", "Work 1 desc", work(3),
)
Total hours: #total_hours

My bad and I found solution. Documentation is still confusing to me. For future reference.

#let total_hours = state("total_hours", 0)
#let work(hours) = [
    #total_hours.update(x => x + hours)
    #hours hours
]

#table(
    columns: (auto, 1fr, auto),
    inset: 5pt,
    [*Name*], [*Desc*], [*Time*],
    "Work 1", "Work 1 desc", work(3),
)
Total hours: #total_hours
