The author informs of a confirmation of a decision to hold The 5th International Symposium on "System and Theoretical programming" in October 1989, in Kishinev. He asks the addressee to make remarks and proposals. A substantiation of holding a symposium is attached.

The author thanks for information on the sympozium "System and Theoretical programming", but for the present he can not define the extent of his participation. (Handwritten and typewritten variants)

Request to give an opportunity to present at the Department's seminar the dissertation "Multilingual translating processors". Reqiest to Ershov to be the official opponent in case of favorable appraisal
