First of all, ⎕FIO does not exist in any other APL interpreter I know of.
Portability of what ?
Portability of any workspace/package that uses FILE_IO workspace. If you have
a package/workspace that uses FILE_IO workspace, you can expect this
package/workspace work in other APL implementation without any modification, as
long as someone create a FILE_IO workspace for that APL implementation which
could employ non-portable bits of that implementation.
