| OP_OPT | Set runtime options | ||
| OP_CIRC | Start of line - varies with multiline switch | ||
| OP_DOLL | End of line - varies with multiline switch | ||
| OP_ANY | Match any character | ||
| OP_CHARS | Match string of characters | ||
| OP_NOT | Match anything but the following char | ||
| OP_STAR | The maximizing and minimizing versions of | ||
| OP_MINSTAR | all these opcodes must come in pairs, with | ||
| OP_PLUS | the minimizing one second. | ||
| OP_MINPLUS | This first set applies to single characters | ||
| OP_QUERY | |||
| OP_MINQUERY | |||
| OP_UPTO | From 0 to n matches | ||
| OP_MINUPTO | |||
| OP_EXACT | Exactly n matches | ||
| OP_NOTSTAR | The maximizing and minimizing versions of | ||
| OP_NOTMINSTAR | all these opcodes must come in pairs, with | ||
| OP_NOTPLUS | the minimizing one second. | ||
| OP_NOTMINPLUS | This first set applies to "not" single characters | ||
| OP_NOTQUERY | |||
| OP_NOTMINQUERY | |||
| OP_NOTUPTO | From 0 to n matches | ||
| OP_NOTMINUPTO | |||
| OP_NOTEXACT | Exactly n matches | ||
| OP_TYPESTAR | The maximizing and minimizing versions of | ||
| OP_TYPEMINSTAR | all these opcodes must come in pairs, with | ||
| OP_TYPEPLUS | the minimizing one second. These codes must | ||
| OP_TYPEMINPLUS | be in exactly the same order as those above. | ||
| OP_TYPEQUERY | This set applies to character types such as \d | ||
| OP_TYPEMINQUERY | |||

| OP_KET | End of group that doesn't have an unbounded repeat | ||
| OP_KETRMAX | These two must remain together and in this | ||
| OP_KETRMIN | order. They are for groups the repeat for ever. | ||

| OP_ASSERT_NOT | Negative lookahead | ||
| OP_ASSERTBACK | Positive lookbehind | ||
| OP_ASSERTBACK_NOT | Negative lookbehind | ||
| OP_REVERSE | Move pointer back - used in lookbehind assertions | ||
