Dec

This decreases the value of %var by value.

/dec [-cszuN] <%var> [value]

Options explained:

uN - decreases %var once and unsets it N seconds later.
z  - decreases %var until it reaches zero and then unsets it.
s  - displays action in status window
c  - decreases %var once per second.

If no value is given, default value is 1.

Example

This example shows how to use dec basically in a while-loop:

var %i = 10
while (%i) {
  echo -ag $chr(37) $+ i = %i
  dec %i
}
