为我提供了以下代码，以分析和了解其功能。我面临的挑战是我什至不知道使用哪种编程语言编写代码。
这是代码段：
**REGOPT** (PVCALC, PVPRINT, STARS);
SET NN = 100; SET X12 = 0.99; SET TT =0;
SET RR = 50; SET SE = 10;
SET B0 = 14; SET B1 = 5; SET B2 = 2; SET B3 = 6;
MMAKE B B0 B1 B2 B3;
SET NOLS = 0; SET NGRM = 0; SET = NORKH =0; SET NMARM0 =0;
SET NMARM1 = 0; SET NMARM2 = 0; SET NMARM3 = 0; SET NMARM4 = 0;
SET NMARM5 = 0;
SET NMARM6 = 0; SET NMARM7 = 0; SET NMARM8 = 0; SET NMARM9 = 0;
