§ 4.89 - [stage] Built-InMnemonic aid: stage for STAGEd loop operations See also: [abs] , [add] , [dec] , [div] , [inc] , [int] , [max] , [min] , [mul] , [random] , [round] and [sub] Allows you to produce values through a range from start to end by specifying how many steps there are in the range, and what step to produce a floor(integer) or floating point result for. mode= is integer by default, and digits= (fractional part of float result) is 2 by default. This built-in is generally intended to be used with [repeat] In the example below, there are four styles that together make up a very controllable looping construct. In {mitt} , the output of the series as generated by [stage] is caught and you can do whatever you like with it. Here, {mitt} just outputs it (and snoops on and adjusts the displayed value of) the iterated counter variable, mycount, but obviously the number of uses for loops are endless.
