If you use the CRE, locations G[0] and G[1] are not available for your data.
References to 'G', 'L', or 'S' are not portable to future software platforms.
'G' Denotes global addressing relative to G[0]
'L' Denotes local addressing relative to L[0]
'S' Denotes top-of-stack addressing relative to S[0]
0 through 255 For 'G' addressing
–255 through 127 For 'L' addressing
–31 through 0 For 'S' addressing
