Request to SAS: Please provide, in every SAS version, a tool to convert files/catalogs between 32 and 64 bit (without the need to buy a licence for a new 'SAS module'). This should not be a problem for experienced (SAS) programmer.
If you are talking about SAS catalogs, data sets and libraries look into Proc CPORT running on a 32-bit session of SAS to create a transport file then read the files with Proc CIMPORT. Best to do this before losing the SAS license on the 32-bit machine that created these. Or vice versa though some items in 64-bit files will not have corresponding behavior in 32 bit results.
Been around for quite awhile. Also the proper way to transfer files into native format between different operating systems.
I don't think it is as easy as it sounds. There are OS differences as well. In any case 32-bit SAS is becoming rarer and rarer so the conversion problem is likely to disappear before too long and just leave OS differences.
