Chapter 13/ The DEBUG Utility
LOAD
L [address[drive sector sectorcount]]
Loads a file into memory.
Parameters
address is the beginning memory location for a file load.
drive sector is the absolute disk sectors that contain the file to
be loaded.
sectorcount is the number of disk sectors to be loaded.
Notes
• Before a file can be loaded, it must have been named either
when DEBUG was started or with the Name command. Both
procedures format a filespec properly in the File Control Block
at CS:5C.
• If you omit all parameters, DEBUG loads the file into memory
at address CS:I00 and sets BX:CX to the number of bytes
loaded. If you specify address, DEBUG loads the file beginning
at the specified address in memory. In both cases, the file is
read from the drive specified in the filespec or from the
default drive if no drive was specified.
• When all parameters are specified, absolute disk sectors are
loaded. The sectors are loaded from the specified drive
(0
=
Drive A, 1
=
Drive B, and so on). DEBUG begins loading
with the specified sector and continues until the number of
sectors indicated by sectorcount have been loaded.
• When an offset is used for the starting address, the segment
indicated by register CS is used.
