[en] SAMPO is a Fortran IV program for performing computer analysis of Ge(Li) gamma-ray spectra. It can also be used to analyze conversion electron spectra. Presented here is a modified version of SAMPO for use on an interactive Tektronix graphics terminal utilizing the IBM Time Sharing Option (TSO). The system consists of a Tektroniz 4010-1 terminal and 4631 hardcopy unit connected via TSO to the LSU IBM 3033 Central Computer. This program was assembled to serve as a precision spectrum analysis routine. The basic mathematical structure of SAMPO was not altered, but the input and output modes of operation were. There are two basic modes of operation: command mode and cursor mode. In command mode one uses the command structure and code words of SAMPO; in the cursor mode one uses single-key commands to perform a variety of different operations. Many of these use the position of the cursor as input data for the operation to be performed. One should be familiar with SAMPO before attempting to use this document. The command structure presented is complete in that it contains the unrevised and revised SAMPO command structure as well as the new functions specific to the present application. 23 figures
