In this example, the If command can be anywhere in the loop. When the If command is: At the beginning of the loop The loop is: Executed only if the condition is true. At the end of the loop Executed at least once and repeated only if the condition is true. The If command could also use a Goto command to transfer program control to a specified Lbl (label) command. Repeating a loop immediately The Cycle command immediately transfers program control to the next iteration of a loop (before the current iteration is complete). This command works with For...EndFor, While...EndWhile, and Loop...EndLoop. Lbl and Goto loops Although the Lbl (label) and Goto commands are not strictly loop commands, they can be used to create an infinite loop. For example: Lbl START Goto START -------- As with Loop...EndLoop, the loop should contain commands that let the function or program exit from the loop. Changing mode settings Functions and programs can use the setMode() function to temporarily set specific calculation or result modes. The Program Editor's Mode menu makes it easy to enter the correct syntax without requiring you to memorize numeric codes. Note: Mode changes made within a function or program definition do not persist outside the function or program. Setting a mode 1. Position the cursor where you want to insert the setMode function. 2. From the Mode menu, select the mode to change, and select the new setting. The correct syntax is inserted at the cursor location. For example: 700 Programming
