I assume you are talking about character type values.

Then you may check for occurs("-",value)>0 or just use:
value= chrtran(value,"-","")

To append 0's you may use padl() or padr() functions, like:
value=padl(value,Length_you_need,"0")

>1. How can I check to see which format it is arriving in?
>
>2. Based off the format that it arrives in, be able to appen 0's to those particular records that dont fill all the way (i.e. 123456, or 1234-56)
