How to get a random number in pascal?

I want to get a random number in pascal from between a range. Basically something like this:

r = random(100,200);

The above code would then have a random number between 100 and 200.

Any ideas?

The built in pascal function only lets you get a number from between 0-your range, while i need to specify the minimum number to return

Just get a random number with the correct range (ie 100 to 200 would be range 100) then add the starting value to it

So: random(100) + 100 for your example

As already pointed out, you should use

myrandomnumber := random(span) + basenumber;

However, to get better quality random numbers, you should call

randomize();

once, on start of your application, to initialize the random number generator.

Couldn't you just declare a starting variable and an end variable and pass random those? e.g.

var
varMyRandomNumber, x, y := extended;

begin

x := 100;
y := 200;

varMyRandomNumber := random(x,y);
ShowMessage(IntToStr(varMyRandomNumber));
end;

?

There's a good example here of using a for loop to set starting and end values : http://www.freepascal.org/docs-html/rtl/system/random.html
