how do I create a permanent dataset from ebcidic file?

[lleemon]

I have an ebcidic file and am given the positions to each field.
filename: srcfile.dat
field1: Key
field2: ID
field3: Num

Start-End-Length for the above fields:
1-19-19 Key
20-44-25 ID
45-63 19 Num

What is the sas code to create a dataset from this information?

Thanks.
