GET BIT
GET BIT bitpos OF byte_string INTO val.
Effect
This statement reads the bit at the bit position bitpos of the data object byte_string and assigns its value to the target field val. val can be specified as follows:
- An existing variable that expects the data type i.
- An inline declaration DATA(var) or FINAL(var), where a variable of type i is declared.
The data object byte_string must be byte-like.
Bit,
constructor and
table expressions can be used. bitpos is a
numeric
expression position of operand type i. The value of bitpos must be greater than 0, otherwise uncatchable exceptions are raised. The bit positions in byte_string are counted from left to right, starting with the
most significant
bit (MSB) of the data object. If the value of bitpos is greater than the number of bits in byte_string, no bit is read and sy-subrc is set to 4.
System Fields
| sy-subrc | Meaning |
| 0 | The value of the bit at position bitpos of byte_string was placed in the result field val. |
| 4 | The value of bitpos is greater than the number of bits in byte_string and no bit was read. |
Notes
- If byte_string has the deep type xstring, a bit is read from the referenced byte string, not from the reference.
- The reading of single bits is especially intended for evaluating the results of bit expressions.
- Counting the bits from the most significant bit (MSB) can have unexpected results when working with components that count from the
least significant bit (LSB).
The hexadecimal value "1B" is assigned
to the data object hex and its bits are read from front to back. The output is "00011011", which
corresponds to the binary representation of decimal 27 or hexadecimal "1B".

Example
Hexadecimal values are assigned to data objects and included in an internal table which is looped across.
During the loop, the bits are read from front to back. Finally, the result is added to the internal
table which shows the hexadecimal and binary values. The GET BIT statement demonstrates a table expression following OF.
Exceptions
Non-Catchable Exceptions
- Cause: n is smaller than or equal to 0.
Runtime Error: BIT_OFFSET_NOT_POSITIVE
