[3.6.0-rc.2] error: Unexpected characters after expression

Ones more

I have the following 0:/macros/Lights/set.g to control two different lights at my machine:

; call this to set any light to a given value or call this to turn off all lights
; can be called with parameter D: String of the device (light) you want to control ("main", "head"), all if permitted
; can be called with parameter B: Power the given light is set to, 0 if permitted

; create var for power and check input for out of bound
var power = 0
if exists(param.B) && param.B >= 0 && param.B <= 1:
    set var.power = param.B

; set each device accordingly
if !exists(param.D) || param.D == "main":
    M42 P0 S{var.power}

if !exists(param.D) || param.D == "head":
    M42 P1 S{var.power}

When executing thjs via M98 P"0:/macros/Lights/set.g", I get the following:
Error: in file set.g line 8: Unexpected characters after expression

With 3.5.4 this macro executed without any warning or error.

Any idea on that?

@marvineer Try removing the colon ":" at the end of each of the if statements. See: https://docs.duet3d.com/User_manual/Reference/Gcode_meta_commands#conditional-construct
