Comments in ILE RPG applications that use SQL
In addition to SQL comments (--), ILE RPG comments can be included within SQL statements wherever SQL allows a blank character.
Fixed-form RPG
To embed an ILE RPG comment within the SQL statement, place an asterisk (*) in position 7.
Free-form RPG
Bracketed comments (/*...*/) are allowed within embedded SQL statements whenever a blank is allowed, except between the keywords EXEC and SQL. Comments can span any number of lines. Single-line comments (//) can also be used.
