Hi

i have a variable card1, i need a msgbox that shows the variable -1
something like:

card1=5
card2= %card1%-1
{
MsgBox, %card2%
}

this has to be very simple but i cant figure it out,
hope someone can solve this for me

card1 := 5
MsgBox % card2 := card1 - 1

Or even

card1 := 5
MsgBox % --card1
card1 := 5
MsgBox % card1 -=1

Or force an expression

card1=5
card2= % card1 -1
MsgBox, %card2%

But variable assignment is here done with legacy syntax ( = )... better use the other suggested ways (expression syntax := )

variable -1
