Repeats a statement for each foreign key column in a table.
In a trigger for the table TITLEAUTHOR, the following macro:
message .FKCOLN("'%COLUMN% is a foreign key column'","",",",";")
generates the following trigger script:
message 'AU_ID is a foreign key column, TITLE_ISBN is a foreign key column;'
For columns, the macro FKCOLN only accepts the variable %COLUMN%.
