ternary operator equivalent

[James C. Fuller]

Charles,
  Does O2 have a ternary operator equivalent?

Code Select Expand

int a = 10, b = 20, c;

c = (a < b) ? a : b;

printf("%d", c);

Hi James,

It can be done with macro functions (the C ternary syntax proved to be too messy)

Code Select Expand

macro iif int(r,  e,a,b)
========================
if e
  r=a
else
  r=b
endif
end macro
'
int a = 10, b = 20

print iif(a < b , a , b)

Good morning,

Charles you example doesn't Work Here Got an Error message in
Print iif(a<b,a,b) ' Not found [a

Here's another example

Code Select Expand

' o2-tenary-frank c to oxygen
uses console

''
'' int a=10, b=20,c;
'' if(a<b){c=a}
'' else{c=b}
'' printf("%d",c)


Dim a As Integer = 10
Dim b As Integer = 20
Dim c As Integer

If a < b Then
    c = a
Else
    c = b
End If

Print c 'result 10

wait

It works here. I also tested it with a console:

Code Select Expand

uses console

macro iif int(r,e,a,b)
========================
if e
  r=a
else
  r=b
endif
end macro
'
int a = 10, b = 20

print iif(a < b , a , b) cr
wait
