Definition
INITCODE causes LOC86 to create a new segment that contains code to initialize
the segment registers. The optional address argument specifies the physical address
of the code that performs this initialization. If no address is specified, the initializa-
tion code will be placed at 200H. The equivalent assembly language code is shown
below:
STACKFRAME OW

OATAFRAME OW

MOV SP,
stack offset

MOV ES, CS:EXTRAFRAME

Notes
• The initialization code segment is created only if a register initialization record
for 8086 segment registers exists in the input. These register initialization
records are automatically produced by 8086-based translators for main
modules.
• If the area of memory used by the INITCODE default is reserved, LOC86
places the initialization code above the reserved space.
• If created, the new segment is called ?'!LOC86_INITCODE.
