4.88 - [stage] Built-In

Mnemonic aid: stage for STAGEd loop operations

See also:  [abs] ,  [add] ,  [dec] ,  [div] ,  [inc] ,  [int] ,  [max] ,  [min] ,  [mul] ,  [random]  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.
