Delimiters are used to distinguish SQL calls from the rest of the program. Delimiters and methods differ considerably by language. For all languages using the standard precompiler, however, the methods are very similar. For example, use EXEC SQL and END-EXEC to delimit an SQL statement in a COBOL program:
EXEC SQL A SQL statement END-EXEC.
For REXX, precede the statement with EXEC SQL. If it is in a literal string, enclose the statement in single or double quotation marks.
