& & !- L & %1L2 If i holds: 1 2 3 4 7 8 9 10 Then XEQ(i) calls: LBL A LBL B LBL C LBL D LBL G LBL H LBL I LBL J To: Compute yˆ for straight-line model. Compute yˆ for logarithmic model. Compute yˆ for exponential model. Compute yˆ for power model. Compute xˆ for straight-line model. Compute xˆ for logarithmic model. Compute xˆ for exponential model. Compute xˆ for power model. Example: Loop Control With (i). An index value in i is used by the program "Solutions of Simultaneous Equations - Matrix Inversion Method" in chapter 15. This program uses the looping instructions L and L in conjunction with the indirect instructions 1L2 and !1L2 to fill and manipulate a matrix. The first part of this program is routine A, which stores the initial loop-control number in i. Program lines: (In RPN mode) Description: L The starting point for data input. Loop-control number: loop from 1 to 12 in intervals of 1. Stores loop-control number in i. The next routine is L, a loop to collect all 12 known values for a 3 × 3 coefficient matrix (variables A - I ) and the three constants ( J - L ) for the equations. Programming Techniques 13-23
