Refusing to give up, the Senate yesterday evening passed and sent to the House a compromise version of a bill giving the president authority to control strategic exports to Soviet bloc nations.

The Senate-passed bill left out two controversial provisions -- an increased role for the Pentagon in licensing strategic exports, which the House has opposed and which kept the bill tied up in conference for five months, and a ban on new bank loans to the government of South Africa. Some Senate members of the conference developed second thoughts over the House-supported sanctions for South Africa even though they won committee approval last week,

It remained unclear what the legislation's fate will be in the House, where congressmen appear to be in a take-it-or-leave-it position with no time to make changes and get it back to the Senate before Congress' scheduled adjournment today.

Some House members were reported upset with the Senate action dropping the sanction on South Africa even though the Senate added some teeth to a provision pressing American companies doing business in that racially-segregated nation to apply fair employment practices.

The administration, meanwhile, was reported by Senate sources to oppose the bill even though, in the absense of legislation, the president is forced to depend on emergency powers for exports controls.
