Registers
| SHL | shift left |
| SHR | shift right |
| ROL | rotation left |
| ROR | rotation right |
Below are advanced functions for register manipulation:
| MBShift | multibyte shift / rotate |
The following functions enable bit to bit operations on a 8 bit to 32 bit integers:
| AND_MASK | Boolean AND |
| OR_MASK | Boolean OR |
| XOR_MASK | exclusive OR |
| NOT_MASK | Boolean negation |
The following functions enable to pack/unpack 8, 16 and 32 bit registers
| LOBYTE | Get the lowest byte of a word |
| HIBYTE | Get the highest byte of a word |
| LOWORD | Get the lowest word of a double word |
| HIWORD | Get the highest word of a double word |
| MAKEWORD | Pack bytes to a word |
| MAKEDWORD | Pack words to a double word |
| PACK8 | Pack bits in a byte |
| UNPACK8 | Extract bits from a byte |
The following functions provide bit access in 8 bit to 32 bit integers:
| SETBIT | Set a bit in a register |
| TESTBIT | Test a bit of a register |
The following functions have been deprecated. They are available for backwards compatibility only. The functions listed above should be used for all current and future development.
| AND_WORD | AND_BYTE |
| OR_WORD | OR_BYTE |
| NOT_WORD | NOT_BYTE |
| XOR_WORD |
XOR_BYTE |
| ROLW | RORW |
| ROLB | RORB |
| SHLW | SHRW |
| SHLB | SHRB |
