Date Stamping

To utilise date stamping in the Grade Control module, you will need to use the available _date variable. This special variable will return an 11 alphanumeric character string in the dd-mm-yyyy format, For example, 01-Jan-2003.

The following synonyms can then be used in the header table:

• date_holes_updates
• date_blast_solid_updated
• date_grade_blocks_updated
• date_bounds_updated
• date_reconciliation_updated

Note T hese synonyms should be set as non-primary variables, with appropriate rules (that is, if 1 then _date).

Unlike other variables in the blast header table, these synonyms will be nulled if no data of the appropriate type (that is, grade blocks, holes etc.) is present in the blast, and updated accordingly when the appropriate type is present.

For example, if the currently loaded blast does not contain any grade blocks, then the corresponding date_grade_blocks_updated variable will be nulled. However, if grade blocks are added to the blast, then the current date will be assigned to the variable.
