The standard Japanese だ, when used as an assertion, may become や in Kansai-ben. With this, the standard Japanese conditional だったら may become やったら in Kansai-ben, and similarly the conjecture だろう may become やろ(う).
Although Kansai-ben has the conditional clause __と__ like in standard Japanese, the negative form Vんと can have a different function depending on the intonation.
In Kansai-ben, the conditional clause (れ)ば is rarely used. Instead, the conditional clause たら is heavily used--to the extent that it is often used in cases where it would be not consider appropriate in standard Japanese.
