Next, up to 63 word arguments may be placed on the stack. The caller then adds the number of arguments to the MARK opcode and pushes that result on the stack. The value of SP is copied to R5. Finally, a JSR PC,address is executed to call the subroutine. After executing its code, the subroutine terminates with an RTS R5. This loads the value in ...
JSR, in the general subroutine branch form, is two bytes and can access any memory location directly. JSRP is a single-byte form of subroutine branch that can access only the locations in the third 64-byte page. This page is called the subroutine page or page 2, numbered from zero. A JSRP cannot be coded from inside page 2 or 3.
When executing JSR (jump to subroutine) and RTS (return from subroutine) instructions, the return address pushed to the stack by JSR is that of the last byte of the JSR operand (that is, the most significant byte of the subroutine address), rather than the address of the following instruction.
An indirect branch (also known as a computed jump, indirect jump and register-indirect jump) is a type of program control instruction present in some machine language instruction sets. Rather than specifying the address of the next instruction to execute , as in a direct branch , the argument specifies where the address is located.
An example is the Java Portlet Specification. A Java portlet resembles a Java Servlet, but produces fragments rather than complete documents, and is not bound by a URL. A Java Portlet Specification (JSR) defines a contract between portlets and the portlet container. JSRs provides a convenient programming model for Java portlet developers.
