USING statements

These statements define base register usage. Up to 256 USING statements may be entered. These statements permit the Disassembler to convert explicit base-displacement addresses to symbolic labels. Labels created within the program is 7 characters long. The first character is 'A', followed by the 6-hex-digit offset to the label. A USING statement must be entered for each DSECT to be used.
