Setting PWM, must use 'L'?

I'm looking at some example code and I keep seeing something like this

Code:

set_pwm1_duty(256L);

what does that L do for the value?
also, how would I be able to integrate it into a variable? obviously compiling something like

Code:

int16 value = 256;
set_pwm1_duty(valueL);

does not work. thanks in advanced.

See this thread and the links in it. http://www.ccsinfo.com/forum/viewtopic.php?t=17729&start=12

Whatever meaningful has been said in the linked threads, it doesn't
change the fact that the below lines produce identical code.

Code:

set_pwm1_duty(256L);
set_pwm1_duty(256);

In contrast, this two are different

Code:

set_pwm1_duty(255L);
set_pwm1_duty(255);

Unfortunately, also the previous threads have some similar (and also inapproriate) examples.
