;is a bug?: if Structure Variables use "="

Structure MyPoint
 x.l 
 y.l
EndStructure

LeftPoint.MyPoint\x = 10
LeftPoint\y = 20

RightPoint.MyPoint = LeftPoint

Debug RightPoint\y
Debug "---------"

If RightPoint<>LeftPoint:Debug "is a bug?"
 Else:Debug "no bug?"
EndIf

Not a bug. You are comparing 2 pointers to the structures LeftPoint and RightPoint.
They are not equal.

for Structure Variables content , now can use :
a=b
can't use :
If a=b ;and <>,>,<,>=,<=

[mk-soft]

Only without strings, arrays, lists

Code: Select all

Structure MyPoint
    x.l 
    y.l
  EndStructure
  
  LeftPoint.MyPoint\x = 10
  LeftPoint\y = 20
  
  RightPoint.MyPoint = LeftPoint
  
  Debug RightPoint\y
  Debug "---------"
  
  If CompareMemory(RightPoint, LeftPoint, SizeOf(MyPoint))
    Debug "Ok"
  Else
    Debug "False"
  EndIf

@skywalk：
if is pointers, best use @
@mk-soft:thanks!

@skywalk：
if is pointers, best use @

There is no if. The structure variable = @structure variable.

Code: Select all

Define.POINT x,y
x\x = 1
y\y = 2
y = x
Debug Bool(x = @x)

There is no deep memory compare function for complex structures. You must code that.

@skywalk：thanks!
I not like to has 'x = @x'
