The operation Table find search in the table (TBL), starting from the record specified from INDXIN, the value (PTN) corresponding to the research criterions pointed out from CMD. The command parameter (CMD) is assigned to a numeric value comprised from 1 to 4, corresponding respectively to the relations =, <>, < and >. If it’s found a record in the table corresponding to the research criterion, it is pointed by INDXOUT. To search the next corresponding record you need to increase INDXIN before recalling again the operation Table find. If there are no records corresponding to the research criterion, INDXOUT will get a value of zero.
