PRINCETON, N.J.--Princeton students last week protested Princeton's refusal to divest its Citicorp stocks, and vowed to continue daily marches on campus until the end of the semester.

Chanting slogans like "no more loans for guns and tanks, total divestment begins with the banks," members of the People's Front for the Liberation of Southern Africa protested the university's refusal to sell the three million dollars worth of stocks in Citicorp, which makes loans to the South African apartheid government.

The Front sponsored marches outside the president's office for 55 days in 1978, and 60 days in 1979. A spokesman said the marches will continue this spring until May.
