SHIFT( ) function

Returns a single character string with the bits in the first character of the input value shifted to the left or right.

Syntax

SHIFT(character, number_of_bits_to_left)

Parameters

character

Character. The value to shift bits for.

number_of_bits_to_left

Numeric. Specifies the number of bits to shift the character value. If the value is positive character is shifted to the left, and if the value is negative character is shifted to the right.

Output

Remarks

You can use this function in conjunction with the BYTE( ), CHR( ) and MASK( ) functions to isolate and move individual bits in a record.

If the value of the number_of_bits_to_left parameter is greater than 15 or less than -15 the result is binary zero, CHR(0).
