\dostepwiserecurse
Syntax
| \dostepwiserecurse{start}{stop}{step}{commands} | |
| {start} | Initial value of recurselevel |
| {stop} | Stop when recurselevel is higher than this (or when lower, if step is negative) |
| {step} | Increment recurselevel by this much after each iteration |
| {commands} | Commands or text to repeat |
Description
Repeat something for start, start + step, start + 2*step, ..., continuing until stop is exceeded.
Example
Counting down: \dostepwiserecurse{10}{4}{-2} {\recurselevel...\ } Counting stopped. Counting down again: \dostepwiserecurse{10}{5}{-2} {\recurselevel...\ } Counting stopped.
