Hi,
I am trying to learn crystal and need to understand more what the step clause does in a loop. Is it possible someone could help and clearly be able to explain it. In the documatation the following code is shown but I dont get what the step command does:
numbervar index;
stringvar display_region := "";
for index := 1 to count({?Selected Region}) step 2 do
(
display_region := display_region + ", " + {?Selected Region}[index]
);
mid(display_region,3);
Thanks
