The INTERRUPT statement is an assembly routine for accessing computer information registers.
Syntax
Legacy support
- Registers are emulated in QB64 to allow older programs to be compiled. To enable mouse input in your programs, the recommended practice is to use _MOUSEINPUT and related functions.
Parameters
- Registers are emulated in QB64 and there is no support for intNum 33h mouse functions above 3 or intNum requests other than 33.
- inRegs are the values placed into the call and outRegs are the register return values.
QBasic/QuickBASIC
- Available in QuickBASIC versions 4 and up and required an external library to be loaded. QB64 emulates the statement without an external library.
- intNum is the interrupt reference vector table address. For historic reference, see: Ralf Brown's Interrupt List
- The TYPE definition below will work for both INTERRUPT and INTERRUPTX statement calls
- INTERRUPT can use all of the below TYPE elements when they are required.
TYPE RegTypeX ax AS INTEGER bx AS INTEGER cx AS INTEGER dx AS INTEGER bp AS INTEGER si AS INTEGER di AS INTEGER flags AS INTEGER ds AS INTEGER es AS INTEGER END TYPE |
DIM SHARED inregs AS RegTypeX, outregs AS RegTypeX |
- QBasic's RegType.BI $INCLUDE file can be used by INTERRUPT or INTERRUPTX
