e.print(param1,param2):By param1 and param2 printing displays.Param1 is variable name, param2
It is character string, as prompt message.
f.add(param1,param1):Param1 value is added into param1, and is assigned to param1.Param1 is variable
Name, param2 can be integer value or variable name.
g.minus(param1,param2):Param1 value is subtracted into param1, and is assigned to param1.Param1 is
Variable name, param2 can be integer value or variable name.
h.multiply(param1,param2):Param1 value is multiplied by param2, and is assigned to param1.param1
It is variable name, param2 can be integer value or variable name.
i.divide(param1,param2):By param1 value divided by param2, and it is assigned to variable param1.
Param1 is variable name, and param2 can be integer value or variable name.
j.mod(param1,param2):By param1 to param2 remainders, and it is assigned to variable param1.Param1 is
Variable name, param2 can be integer value or variable name.
Wherein, control flow statement grammer is as follows：
k.if(exp){statement1}else{statement2}:Exp is expression formula, and expression formula result is true, is performed
Statement1 statement blocks, statement1 statement blocks are otherwise skipped, perform statement2 statement blocks.
l.while(exp){statement1}：Exp is expression formula, first determines whether expression formula, and IF expression result is
Very, then loop body statement1 is performed, has performed statement1, program returns to test condition, and expression formula is carried out again
Assess, loop body is performed again if result is very, until test result is false, then skip the journey of loop body execution below
Sequence.
Following is the scripted code fragment using the specific grammer Standard compilation：
Its each sentence is explained as follows：
1. stating a variable a, and by mode (pattern) attribute of current component, it is assigned to a.
2. variable a value is arranged to integer 3.
3. a value is judged, if a>=100, then 4 are performed, otherwise performs 5.
4. the first layer layer of current component hidden attributes are arranged into 1, represent to hide the layer.
5. order performs 6.
6. the first layer layer of current component hidden attributes are arranged into 0, represent to show the layer.
7. terminate.
