Sure thing.

Like this:

:Goto 1
:Lbl 2
:<subroutine here>
:End
:Lbl 1
:<code here>
:If <want to run subroutine>
:Then
:For(A,-1,0)  //CLOSE THIS!
:If A
:Goto 2
:End
:End
:<code here>

Hey i made my own version of Calcalc, do you mind if i post it?

Yeah its Basic, and pretty fast if i do say so myself.  Here are the programs, run Calc to run the program.  Syntax is very loose, but there are no lowercase, since i thought that it would be more hassle than its worth to type them in, plus when the program is compiled into a single program, it means that there will be only a single program (about 1000 bytes).  These next aexpressions are all legal:

5M TO CM
5M TO CM
5 M TO CM
5(M) TO CM

It currently supports these units, although adding more is trivial:
Meters  (m)
Centimeters (cm)
Milimeters (mm)
Kilometers (km)
Inches (in)
Feet (ft)
Yards (yd)
Miles (Ml)
Kilograms (KG)
Grams (G)
Pound mass (lbm)
Ounce (oz)
Newton (n)
Pascal (pa)
PSI (psi)
Joules (j)
Electron Volts (ev)
Seconds (s)
Minutes (min)
Hours (h)
Pound Force (lbf)
Watts (w)
KiloWatts (kw)
Volts (v)
KiloVolts (kv)
Ohms (ohm)
Amps (a)
The program is also written so that adding extra units does not impact speed very much at all.  It does have some load time at startup though.  I wanted to keep size at a minimum so it precalculates a lot of data.

EDIT: Also note that i dont do any unit checking so it lets you do silly things like convert feet to seconds

wow nice Builderboy!

Don't worry, I'm never gonna give this up Calcalca is still on my calculator (in the form of a group), but I'm not going to be working on it for a while (I've put it in "indefinite hold" mode).

The biggest problem right now is the speed, as everyone will probably notice. I like the way your program converts the data to a list at startup, but for me to do that, I'd have to use at least five lists and two matrices, which would be both slow to initialize and hard to keep track of.

I probably won't be able to work more on Calcalca until September, since I'm in China right now (away from my calculator for a month and a half -- it's been absolutely horrible), and when I get back in mid-August, there's still a lot to do in terms of my Axe contest entry and a stupid AP Lang summer project.

EDIT: On second thought, I just came up with an idea that would let me start it up faster with only two lists. I'm still probably not going to be working on this for a bit, though.

Yes, they haven't blocked Omnimaga, thankfully, and I don't see any reason for them to. It's not like calculator programming threatens Communist totalitarianism

On the other hand, there's no doubt the Great Firewall exists. I can't access Google Images from any domain, and whenever I try to access a politically opinioned website, even if it's from a link on Google, the page magically doesn't exist.

Earlier in the Firewall's history, the Chinese Internet police actually displayed on some open websites a cute little cartoon mascot of two police officers with the "cute" slogan "Watching you, watching me." I'd give you a link now, but it's blocked too

EDIT: Probably shouldn't even post that. I wouldn't want to get Omni blocked here
