[. . . ] FLOAT ATOF (CHAR STRING[ ]) Parameters: · STRING: An input string containing the character representation of the floating-point number. The result is a 64-bit floating-point number representing the converted string. Any non-numeric characters in the string are ignored. ATOF returns the value representing the first complete set of characters that represents a floating-point value. Valid characters are "0" through "9", ". ", the sign designators ("+" and "-"), and the exponent ("e" or "E"). If no valid characters are found, zero is returned as a result. Num = ATOF('The total = -1. 25e-3')// Num = -0. 00125 ATOL This function converts a character representation of a number to a signed 32-bit integer. SLONG ATOL (CHAR STRING[ ]) Parameters: · STRING: A string containing the character representation of the integer. The result is a 32-bit signed integer representing the converted string. Any nonnumeric characters in the string are ignored. ATOL returns the value representing the first complete set of characters that represents an integer. Valid characters are "0" through "9" and the sign designators "+" and "-". If no valid characters are found, zero is returned as a result. Num = ATOL('Value = -128000') BAND (&) BNOT (~) BOR (|) // Num = -128000 This operator performs a bitwise AND on two data items, which can be constants or variables. This operator performs a bitwise NOT on a constant or variable. This operator performs a bitwise OR on two data items, which can be constants or variables. 102 NetLinx Programming Language Reference Guide Reserved Identifiers Keywords & Run-Time Library Functions (Cont. ) BREAK The BREAK command terminates execution of the current WHILE, LONG_WHILE, or FOR loop and resumes program execution at the first instruction following that loop. BREAK also jumps to the end of a SWITCH statement. WHILE (<condition>) { // statements IF (<condition>) { BREAK // Go to statement: X = X + 1 } } // Execution continues here after BREAK or // after normal completion of the WHILE loop. X=X+1 BUTTON_EVENT This keyword defines a button event handler and can only be used in the DEFINE_EVENT section of the program. This type of handler processes PUSH, RELEASE, and HOLD events. BUTTON_EVENT[DEVICE, CHANNEL] or BUTTON_EVENT [(DEVCHAN[ ])] { PUSH: { // Push statements go here } RELEASE: { // Release statements go here } HOLD[TIME, [REPEAT]]: { // Hold statements go here } } See the Event Handlers section on page 61. BXOR (^) CALL This operator performs a bitwise XOR operation between two data items, which can be constants or variables. [. . . ] Level: A value that is related to an analog input or output on a NetLinx device. Level Event: Triggered by a level change on a particular device. Local variable: A variable declared in a subroutine or function, and whose scope is limited to that subroutine or function and is static. Mainline: The portion of a NetLinx program (DEFINE_PROGRAM) that is executed continuously to service input events and provide feedback to NetLinx devices. [. . . ]
