I have been looking all over the net and have been unable to accomplish something that would take 10 seconds in any programming language...HELP PLEASE

simply, I need to run multiple commands if a value is true or false.
Exampl

if H < 5

x=2
y=9
gg=567
h.3=h.9

If H > 5
x=42
y=93
gg=23567
h.3=h.7

I have seen the commen if function (Condition,TV,FV)
but have not been able to find a away to accomplish what I need to do without writing a if statement for every line.

I have so many lines that are based on conditions that it will be really really sloppy if I have to write a (if) for each line.

Can in any way I run a block of code using a if statement.

I have been looking all over the web and couldnt find an example/answer.
Thanks

z:2,9,567,h.9 (using ALt m)
z2: same idea
z:if(H>5,z1,z2)
x:z[0
y:z[1
gg:z[2
h.3:z[3

is an easy way to only write one 'if'. There is a shorter way, see if you can find it, that needs no 'if' statements at all.

That's probably full of mistakes, for instance the first z should be a z1

Ugggg, to use a if like this do all the items in the matrix have to be the same units of measure?

Im getting an error that units dont match when I populate the matrix with different forumals.

any ideas?

Yes, elements in a matric should have the same units

Oh well, you'll have to do it another way.
