Format of REAL/32 Exec Parameter Block (EPB):
Offset	Size	Description	(Table 04035)
 00h	DWORDDoubleword; four bytes.	 Commonly used to hold a 32-bit segment:offset or selector:offset address.	-> ASCIZA NUL-terminated ASCII string.	The ASCIZ string "ABC" consists of the four bytes 41h, 42h, 43h, and 00h.  Unless otherwise specified, maximum lengths given in the interrupt list do not include the terminating NUL. command to be executed
 04h	BYTE	type of exec

		01h .COM
		02h .EXE
		03h .BAT
		04h RSP-type queue
 05h	BYTE	flags
		bit 0: overlay existing program
		bit 1: don't assign console to child
		bit 2: allocate memory for .CMD within parent's memory space
		bit 3: make full banked window available while loading child
 06h	DWORDDoubleword; four bytes.	 Commonly used to hold a 32-bit segment:offset or selector:offset address.	32-bit offset to ASCIZA NUL-terminated ASCII string.	The ASCIZ string "ABC" consists of the four bytes 41h, 42h, 43h, and 00h.  Unless otherwise specified, maximum lengths given in the interrupt list do not include the terminating NUL. command line
 0Ah	WORD	selector for ASCIZA NUL-terminated ASCII string.	The ASCIZ string "ABC" consists of the four bytes 41h, 42h, 43h, and 00h.  Unless otherwise specified, maximum lengths given in the interrupt list do not include the terminating NUL. command line
