Getting Input

We can get input from the keyboard using

• The Give Command
• The GetChar() Function
• The Input() Function

Give Command

Syntax:

Give VariableName

Example:

See "Enter the first number : " Give nNum1
See "Enter the second number : " Give nNum2
See "Sum : " + ( 0 + nNum1 + nNum2 )

Output:

Enter the first number : 3
Enter the second number : 4
Sum : 7

GetChar() Function

We can get one character from the standard input using the GetChar() function

Syntax:

GetChar() ---> Character

Example:

While True
        See "
                Main Menu
                (1) Say Hello
                (2) Exit
            "
        Option = GetChar()
        GetChar() GetChar()  # End of line

        # the previous two lines can be replaced with the next line
        # Give Option

        if Option = 1
                see "Enter your name : " give cName
                see "Hello " + cName
        else
                bye
        ok
End

Input() Function

We can get input from the keyboard using the Input() function

Syntax:

Input(nCount) ---> string

The function will wait until nCount characters (at least) are read

Example:

See "Enter message (30 characters) : " cMsg = input(30)
See "Message : " + cMsg
