Pop from string lists
|
I'm breaking my head with this, i know it's an easy question, but i can't work it out.
How do i pop a value from a string list variable to another variable? |

#VAR astringlistvariable {item1|item2|item3}
#VAR anothervariable {%pop( astringlistvariable)} |

The problem I have with this is that when the second #VAR command is executed, the value on anothervariable is %pop( astringlistvariable). Meaning that i don't get the value item1 that i want.

I got it to work using %item and #DELN.. not the most elegant solution, but at least works :)

There's nothing wrong with %item and #DELN. That is the method you would use on older versions which don't have %pop, and does precisely the same thing. If the snippet I posted above doesn't work, you probably have one of those older versions.
#VAR anothervariable %item( @astringlistvariable, 1)
#DELN astringlistvariable 1 |

I had a similar problem in some of my variable hand offs. I ended up solving it by putting brackets around the command to make sure it expands before assigning the value to the second variable, like so...
#VAR anothervariable {[%pop( astringlistvariable)]}
