Saving, Restoring, and Modifying Mode Settings Often, programs are designed to run in a specific mode (for example, FIX 4 or RPN). You can L:u use to recall the current mode, save it, modify the settings, either by going in $:u the menu, or using the function and then restoring it. For example: L:u$1 1. recalls and stores the current mode settings in Memory 1. 2. :u4IO selects FIX=4. L1:$:u 3. Your program: restores the mode settings to what they were at the beginning of the program. Lu 4. returns a 12 digit number: CactdmrvAOff. See Table 13-4 for a description of each digit. Table 13-4 Digit Description A is "1" for radian mode, "2" for degree mode. a is "1" in Semi-annual mode, "2" in Annual mode. C is "1" in Standard TVM mode, "2" in Canadian TVM mode. c is "1" in Actual day count mode, "2" in 360 day count mode. d is "1" if the decimal separator is ".", 2 for "," ff is "00" to "11" or "13" and indicates the FIX setting (13 is for FIX=-1). m is "1" for "mm.ddyyyy" mode, "2" for "dd.mmyyyy" mode. O is "1" for Chain mode, "2" for Algebraic mode, and "3" for RPN mode. r defines the regression line type. "1" for a*x+b, "2" for a*ln(x)+b, "3" for b*e(ax), "4" for b*xa, "5" for b*ax, "6" for a/x+b and "7" for ax2+bx+c. t is "1" if thousands separators are not visible, "2" if they are visible. v is "1" for 2 variable statistics, "2" for 1 variable, and "3" for 1 variable frequency. :$:u When using , any illegal value is ignored and this setting will not change. For example: 314:$:u will switch to RPN mode. No other setting will change. 86 Programming
