Variables

A variable is a name that holds a value. Its first character says what kind it is:

Kind	Example	Belongs to	Kept until
Standard	%count	The script, and scripts it starts with call.	The script starts again.
Namespace	!count	The current namespace: this script only, or shared with other scripts.	The script starts again (local) or EasyUO Reforged closes (global).
Persistent	*count	Every script, in this and the original EasyUO.	You change or delete it: it is saved in the registry.
System	#CharName	EasyUO and the client.	Built in; see the variable reference.

Names

• A name is made of letters, digits and _: %loot_bag, %x2. Nothing else, not even a -.
• Case does not matter: %Count and %COUNT are the same variable.
• %0, %1, %2, … hold the parameters of the last gosub or call, so avoid names made of digits only.

set %var Bob
set %Var Joe
display ok %var              ; Joe: %var and %Var are the same variable
halt

Values

• A value is one word. set %a hello world stores only hello. To store several words, write _ between them, or glue them with commas and #SPC: set %a hello , #spc , world.
• Numbers and text are both just values. A value that looks like a whole number (42, -7, $1A) can be used in calculations; anything else counts as 0 there. See Expressions.
• A variable that was never set reads N/A.
• Use a variable anywhere in a line and its value is put in its place before the command runs. The one exception is the variable set and for assign to.

Standard variables: %

Standard variables are the everyday kind. They belong to the running script and are shared with scripts it starts with call. They are all cleared when the script starts again.

Namespace variables: !

!x is the variable x of the current namespace. A script starts in the local namespace std, so until you switch, ! variables behave like % variables. Switch namespaces to give a sub its own variables (namespace local) or to share variables with other scripts running in EasyUO Reforged (namespace global).

Persistent variables: *

Persistent variables survive restarts: they are saved in the Windows registry, under HKEY_CURRENT_USER\Software\EasyUO, and every script on the computer can read them. EasyUO Reforged uses the same place as the original EasyUO, so the two share them.

if *runs = N/A
  set *runs 0
set *runs *runs + 1
display ok This script has run *runs times.
halt

For more data, or data you want to keep in a file of your own, there is also SQL. SQL or * variables? compares the two.

System variables: #

System variables are built in. Most describe the client and your character (#CharPosX, #Hits, #FindID); a few describe EasyUO itself (#Time, #LPC). Most are read-only; the writable ones are marked Read / write. They are listed in the variable reference.
