Saving, Restoring, and Modifying Mode Settings

Often, programs are designed to run in a specific mode (for example, FIX 4 or RPN). You can use L:uto recall the current mode, save it, modify the settings, either by going in the menu, or using the $:ufunction and then restoring it. For example:

1.L:u$1recalls and stores the current mode settings in Memory 1.

2.:u4IOselects FIX=4.

3.Your program: L1:$:urestores the mode settings to what they were at the beginning of the program.

4.Lureturns a 12 digit number: CactdmrvAOff. See Table 13-4 for a description of each digit.
