### bitclear()

#### Syntax

**bitclear**(binary1,firstbitnumber,lastbitnumber)

#### Description

Clears a range of bits (all bits with numbers >=*firstBitNumber* and <=*lastBitNumber*) operating directly on *binary*. Returns a Boolean (true for success).

The function operates directly on the *binary1* argument, and returns 1 for success and 0 for failure. If the bit numbers identify some bits which are outside the current length of the binary field, Omnis extends the field by appending bytes with value zero, and clears the bits.

#### Example

###### Calculate lStatus as **bitclear**(lBinary1,lFirstBitNumber,lLastBitNumber)
