The following is pretty simple and takes advantage of the Stamp's
expression evaluation scheme:
xyz = x * 10 + y * 10 + z

I know this question was answered once before but I thought I'd ask
again....
I have three variables that I want to combine to make a three digit number:
x var 2
y var 3
z var 4
I need the result to be: <234>
I know that:
(x*100)+(y*10)+z=<xyz>
or:
a=x*100
b=y*10
c=z
result = a+b+c
But is there a simpler method?
Thanks in advance,
Dan

I may be off the mark here, but should the above not be: xyz = x * 100 + y
* 10 + z ('hundreds' should be * 100 instead of *10)

Xyz=x*10+y*10+z is the same as:
Xyz = (((x*10)+y)*10)+z
Which is algebraically the same as x*100+y*10+z (using "normal" math
notation).
This is sort of the way you do it in a loop with user input or an array:
Result=0
For i=3 to 0 step -1
Result=result*10
Result=result+x[noparse][[/noparse]i] ' x is the "next number"

When my reply got posted, I thought it looked rude. Sorry about that.
I'll try again, more politely:
The order of operations in the BS2 is purely left to right -- it doesn't
follow the precedence rules we were taught in school (exponents,
mult/div,
add/subtract. Remember that, and you can see why xyz = x * 10 + y * 10
+ z
works.

wanted to assemble the string, "234"
using, say, Qbasic, you could just concatenate. Can you do this with pbasic
commands?

There are no character or string types in PBASIC. The best you can do is use
an array of bytes and put the characters into as you desire. You'll have to
specify the character position in the array; concatenating won't work.
myStr VAR Byte(3)
myStr(0) = "2"
myStr(1) = "3"
myStr(2) = "4"
DEBUG STR myStr\3
