Using partial parametrization as proposed in Algol Bulletin by Charles Lindsey. Algol68G does not support binding ''all'' actual parameters "partially" without deproceduring, so a PROC(BOOL)INT mode is used instead of a PROC INT. The variable ''captured i'' is passed twice, once by reference and once by value, to demonstrate that it is possible to capture both ways, and a little extra code is added to show that the closure can modify the captured variable. |
