DESCRIPTION
Copies memory images to a specified file. The resultant
file will be procedure type, subtype O. The first and last
locations of each memory segment, optional entry point
address (default=O), record length (80H, 100H, 200B,
400B, 800H, or 1000B; default=80B bytes) and stack
size (default=80H bytes) are given in hexadecimal. At least
one but no more than 16 segments may be specified. When
writing the file, the exact memory locations, including
first location and last location, are copied for each
segme~t.
The lowest ana highest memory addresses
referenced by the file are saved in the descriptor record
(refer to Appendix J) and are used by the RIO Executive
whe~
requesting memory allocation prior to loading.

IMAGE TWO.BLOCKS 4400 4425 7000 7FFO E=7000
Copies contents of memory locations 4400 to 4425
and 7000 to 7FFO to file TWO.BLOCKS. The file
