Yes, a few different ways:
1) The entire file is parsed so if you have a word that is available in
0.98 but not in 0.97, you either have to call it dynamically:
"vm-version" "system" lookup-word execute( -- string )
or
2) Make separate files for 0.97 and 0.98, unfortunately we don't have good
version words prior to 0.98, but you could do something like this:
"vm-version" "system" lookup-word [
execute( -- string ) ".factor-rc-" prepend run-file
] [
".factor-rc-0.97" run-file
] if*

Mobile security can be enabling, not merely restricting. Employees who
bring their own devices (BYOD) to work are irked by the imposition of MDM
restrictions. Mobile Device Manager Plus allows you to control only the
apps on BYO-devices by containerizing them, leaving personal data untouched!
