           '-window-'  '-address-'   

window

A Disassembly window. Select by a Window Specification or by placing the cursor in the window. If omitted and the cursor is not in a Disassembly window, uses the first Disassembly window.

address

An address specifying the storage location at which the disassembly listing begins.

If an address is supplied on the command line, or an address can be determined from the cursor position, a disassembly of the indicated memory area is shown.

If no address is supplied, and an address cannot be determined from the cursor position, a disassembly listing is displayed, beginning at the first instruction which previously appeared on the disassembly display.

If the DISASM function is invoked when no Disassembly windows are open, one is opened.

If the DISASM function is invoked when a Disassembly window is open, but no address is specified, the selected window is closed.

If the DISASM function is invoked when a Disassembly window is open, and an address is specified, the starting address of the disassembly in the selected window is changed.

By positioning the cursor in the first halfword of an instruction and pressing DISASM, you can make that instruction the first one displayed.

If the cursor is positioned in the first halfword of the first instruction displayed, and that instruction is a branch, the effective address of that branch instruction becomes the first instruction disassembled.
