Variables

This program supports variables. There are three types of variables:

• USER: Variables created by the user using the var/mov commands. These variables have no access restrictions. You generally only deal with these.
• SYSTEM: Variables created by x64dbg, that can be read and written, but cannot be deleted.
• READONLY: Variables created by x64dbg, that can be read, but not written or deleted.

Setting variables

You can set variables in the following ways:

mov myvar, 1234
mov $myvar, 1234
myvar = 1234
$myvar = 1234

All of the above set a USER variable myvar to the value 0x1234. You can also use the C-style assignment operators (see the expression documentation for a full list of supported operators):

myvar += 0x10
myvar |= 0x10
myvar++
myvar--

Reserved Variables

There are a few reserved variables:

• $res/$result: General result variable.
• $resN/$resultN: Optional other result variables (N= 1-4).
• $pid: Process ID of the debugged executable.
• $hp/$hProcess: Debugged executable handle.
• $lastalloc: Last result of the alloc command.
• $breakpointcondition : Controls the pause behaviour in the conditional breakpoint command.
• $breakpointcounter : The hit counter of the breakpoint, set before the condition of the conditional breakpoint is evaluated.
• $breakpointlogcondition : The log condition of the conditional breakpoint. It cannot be used to control the logging behavoiur.
