# `step.too_many`

More than 8 changing calls on one way through an action.

Area 12, [Jobs and events](../topics/jobs-and-events.md); not declinable; the next step is usually the agent's.

An action makes at most 8 changing calls on one way through it, counting
those of the actions it calls:





```jadpo
use app { sheets }
use bakery/types { PriceList }
use bakery/failures { SheetNotKept }

/// Keeps the week's price sheet for each of the bakery's nine shops.
action share_prices(price_list: PriceList) fails SheetNotKept -> List<File> {
    var bakehouse: File = attempt sheets.put(encoding.to_utf8(price_list), FileType.csv) {
        storage_full: SheetNotKept
    }
    var market: File = attempt sheets.put(encoding.to_utf8(price_list), FileType.csv) {
        storage_full: SheetNotKept
    }
    var station: File = attempt sheets.put(encoding.to_utf8(price_list), FileType.csv) {
        storage_full: SheetNotKept
    }
    var harbour: File = attempt sheets.put(encoding.to_utf8(price_list), FileType.csv) {
        storage_full: SheetNotKept
    }
    var castle: File = attempt sheets.put(encoding.to_utf8(price_list), FileType.csv) {
        storage_full: SheetNotKept
    }
    var bridge: File = attempt sheets.put(encoding.to_utf8(price_list), FileType.csv) {
        storage_full: SheetNotKept
    }
    var mill: File = attempt sheets.put(encoding.to_utf8(price_list), FileType.csv) {
        storage_full: SheetNotKept
    }
    var abbey: File = attempt sheets.put(encoding.to_utf8(price_list), FileType.csv) {
        storage_full: SheetNotKept
    }
    var quayside: File = attempt sheets.put(encoding.to_utf8(price_list), FileType.csv) {
        storage_full: SheetNotKept
    }
    return [bakehouse, market, station, harbour, castle, bridge, mill, abbey, quayside]
}
