What is the IMPORT/ EXPORT form that is not obsolete?

Hi Experts,

Just wanted to know which form of the IMPORT EXPORT statement in ABAP is not yet obsolete? Can I still use below?

IMPORT gv_usage_type = gv_usage_type FROM MEMORY ID 'ZUSAGETYPE'.

EXPORT gv_usage_type = gv_usage_type TO MEMORY ID 'ZUSAGETYPE'.

Thank you.

Regards,

Kath
