str customerName; // data type must be declared

str customerName = "Name"; 

const str constantVariable = "Value";

Primitive Data Types

date
dd/mm/yyyy
 
enum
named list of literals
 
guid
globally unique identifier
 
int
32-bit wide integer
 
int64
64-bit wide integer
 
real
number values with decimals
 
str
String
 
timeOfDay
number of seconds since midnight
 
utcDat­eTime
Combin­ation of 
date
and 
timeOfDay

Access Identi­fiers

[private]
only called in method where declared

Printing Infolog to Screen

info("This is an info log message.");

Error Handling

throw error("This is an error.");

Try...C­atch

try
{
	//Run some code
}
catch (Exception::Numeric)
{
	info('Found a Numeric exception.');
}
catch
{
	info('Caught an exception');
	retry;
}
finally
{
        // Executed no matter how the try block exits.
}
 

Assignment Operators

=
 
int i = 1;
 
+=
 
int i; i=+1;
 
++
 
int i; i++;
 
-=
 
int i; i-=1;
 
--
 
int i; i--;

Arithmetic Operators

<<
 
int a = 1<<2;
\\(1 x 2 x 2)
>>
 
int a = 1>>2;
\\ (1/2/2)
*
multiplies
/
divides
 
div
divides left value by right value
 
mod
divides with a remainder
~
performs a binary 
NOT
operation
&
performs a binary 
AND
operation
^
Binary 
XOR
operation
|
binary 
OR
operation
+
addition
-
subtra­ction
?
 
int x = 4; result = (x ==5) ? "­Yes­" : "­No";

Relational Operators

Like
SQL statement, returns criteria if true
 
==
 
a==b\\ true
 
!=
 
a!=b \\true 
>=
 
a>b
 
<=
 
a<=b
 
>
 
a>b
 
<
 
a<b
 
&&
 
a<b && b>c \\ AND
 
||
 
a>b || b>c \\ OR
 
!
 
a ! b \\ NOT
 

If Statement

if (x == 5)
  {
      info('x equals five');
  }

If...Else Statement

if (x == 5)
  {
	info('x equals five');
  }
else
  {
	info('x does not equal five');
  }

Switch Statement

switch (x){
	case 5:
		//do something
		break;
	case 10:
		//do something
		break;
	default:
		//do something
		break;}

While Loop

int loopCount = 1;
container cont;

while (loopCount <= conlen(cont)) {
	print conpeek(cont,loopCount);
	loopCount = loopCount + 1;
}

For Loop

for (int i=1; i<=100; i+=1){
	print ra[i];
}
