sas automatic compare

[LineMoon]

I have  a sas tables in the sub-folders  like this .

====>> old

old/ F1

old/F2

old/F3

.....

....

......

old/Fn

=====>

new/ F1

new/F2

new/F3

....

....

....

new/Fn

I want to make an automatic compare for all the files  one by one

It means

compare new/F1/ t1 with  old/F1/ t1

               new/F1/ t2 with  old/F1/ t2

               .......................................

              new/Fi/ tj with  old/Fi/ tj

               ......................................

              new/Fn/ t2 with  old/Fn/ t2

Thank you

Use sashelp.vstable to build a call execute (proc compare).
