CALL ABSOLUTE - QB64Official/qb64 GitHub Wiki

CALL ABSOLUTE is used to access interrupts on the computer or execute assembly type procedures.

Syntax

CALL ABSOLUTE([argumentList,] integerOffset)

Legacy Support

• CALL ABSOLUTE is implemented to support older code and is not recommended practice. To handle mouse input, the use _MOUSEINPUT and related functions.

Description

• CALL and parameter brackets are required in the statement.
• argumentList contains the list of arguments passed to the procedure.
• integerOffset contains the offset from the current code segment, set by DEF SEG and SADD, to the starting location of the called procedure.
• QB64 has the ABSOLUTE statement built in and requires no external library, like QuickBASIC did.
• NOTE: QB64 does not support INT 33h mouse functions above 3 or BYVAL in an ABSOLUTE statement. Registers are emulated.
