 QBasic, a popular programming language in the DOS era, lacks native\r
 mouse support. This limitation can be a hurdle for developers looking\r
 to create interactive applications. To bridge this gap, I developed a\r
-solution that involves a Terminate and Stay Resident (TSR) program\r
-written in x86 assembly and a QBasic demonstration program.\r
+workaround that allows QBasic to use mouse input.\r

-The solution comprises two main components:\r
+Workaround to access mouse involves a Terminate and Stay Resident\r
+(TSR) program written in x86 assembly. This TSR program must be\r
+started before running QBasic program that depends on mouse. This TSR\r
+program hooks into the system's interrupt mechanism, specifically the\r
+timer interrupt (IRQ 0), allowing it to regularly check for mouse\r
+activity several times per second.\r
 \r
+When this timer interrupt triggers, the TSR reads the latest mouse's\r
+horizontal and vertical movements and button states using mouse\r
+interrupts. This data is then stored in a dedicated memory location —\r
+a data table within the TSR's memory space. The TSR uses interrupt 79h\r
+as a pointer to this data table, making it accessible to other\r
+programs, including the QBasic application.\r
 \r
-** Terminate and Stay Resident module\r
+While QBasic originally is not able to read mouse, it is able to read\r
+(and write) arbitrary location in system RAM. The QBasic demonstration\r
+program begins by retrieving the address of the TSR mouse data table\r
+from the interrupt vector table using interrupt 79h. By checking a\r
+predefined magic number (1983) in the data table, the program confirms\r
+that the mouse driver is loaded. Once verified, the QBasic program\r
+continuously reads mouse data from this shared memory location, while\r
+TSR keeps updating it with latest mouse state simultaneously.\r
