Option
/DS[[ALLOCATE]]
The /DSALLOC option tells LINK to load all data starting at the high end of the data segment. At run time, the data segment (DS) register is set to the lowest data-segment address that contains program data.
By default, LINK loads all data starting at the low end of the data segment. At run time, the DS register is set to the lowest possible address to allow the entire data segment to be used.
The /DSALLOC option is most often used with the /HIGH option to take advantage of unused memory within the data segment. These options are valid only for assembly-language programs that create DOS .EXE files.
