Perform without dialog prevents display of the Replace Field Contents dialog box when the script step executes.
Specify target field specifies the target field for the replace operation.
Replace with "current contents" uses the current value in the specified field as the replacement value to place in that field in every other record in the current found set.
Replace with serial numbers reserializes the field in every record in the current found set.
Entry options uses the next available value in Entry Options as the first record number, incrementing with whatever value is in Entry Options.
Custom Values lets you enter a value to be used as a starting point for the serialization, as well as a value by which to increment each serialized field in the current found set.
Update serial number in Entry Options? resets the serial number value in Entry Options so that the next serial number that is automatically entered will follow the records you have reserialized with this script step. If this option is not used, the serial value in Entry Options is not changed, and may not be in sequence with the newly reserialized records.
If the field to be replaced was set up for auto-entry of a serial number and Prohibit modification of value is not selected, FileMaker Pro will still put sequential numbers in the selected field, but will do so starting with the next number to be automatically entered.
Replace with calculated result displays the Specify Calculation dialog box, where you can enter a calculation to be used as the replacement value.
