The FIND function determines if an incoming data value is in an indexed FOCUS data source field. The function sets a temporary field to a non-zero value if the incoming value is in the data source field, and to 0 if it is not. A value greater than zero confirms the presence of the data value, not the number of instances in the data source field.
You can also use FIND in a VALIDATE command to determine if a transaction field value exists in another FOCUS data source. If the field value is not in that data source, the function returns a value of 0, causing the validation test to fail and the request to reject the transaction.
You can use any number of FINDs in a COMPUTE or VALIDATE command. However, more FINDs increase processing time and require more buffer space in memory.
Limit: FIND does not work on files with different DBA passwords.
The opposite of FIND is NOT FIND. The NOT FIND function sets a temporary field to 1 if the incoming value is not in the data source and to 0 if the incoming value is in the data source.
FIND(fieldname [AS dbfield] IN file);
