Initialize variables and clean up for batch comparison

Attention : This code requires administrator privileges.

The %AHGinitdiffbatch macro defines the global variables 'batchcompare', 'strold', and 'strnew'. It then performs preventive cleanup by deleting specific temporary files (*.old.sas^© and *.new.sas^©) in the ~/temp/ directory via shell commands encapsulated in the %AHGrpipe macro.
