calling variables

[Guest]

Gintaras, I managed to do what I wanted with following code, but is it the correct way?

Code:

Copy      Help

str num1
num1="4*"
  
str num
num="No#"

num + num1

out num

Edit:

I think I may have found a bug, because the following code spits out an 8 digit number (always starting with "2"), depending on how you do it i.e. num + num1 or num+num1 etc.:

Code:

Copy      Help

str num1
num1="4"

str num
num="No#"

str num2
num2=num + num1

out num2

Just thought I'd let you know because it seems strange.
