Embed SQL statements in PL/I applications that use SQL

The first statement of the PL/I program must be a PROCEDURE statement.

SQL statements can be coded in a PL/I program wherever executable statements can appear.

Each SQL statement in a PL/I program must begin with EXEC SQL and end with a semicolon (;). The key words EXEC SQL must appear all on one line, but the remainder of the statement can appear on the next and subsequent lines.

• Example: Embed SQL statements in PL/I applications that use SQL
  An UPDATE statement coded in a PL/I program might be coded as follows.
• Comments in PL/I applications that use SQL
  In addition to SQL comments (--), you can include PL/I comments (/*...*/) in embedded SQL statements wherever a blank is allowed, except between the keywords EXEC and SQL.
• Continuation for SQL statements in PL/I applications that use SQL
  The line continuation rules for SQL statements are the same as those for other PL/I statements, except that EXEC SQL must be specified within one line.
• Include code in PL/I applications that use SQL
  SQL statements or PL/I host variable declaration statements can be included by placing the following SQL statement at the point in the source code where the statements are to be embedded.
• Margins in PL/I applications that use SQL
  Code SQL statements within the margins specified by the MARGINS parameter on the CRTSQLPLI command. If EXEC SQL does not start within the specified margins, the SQL precompiler will not recognize the SQL statement.
• Names in PL/I applications that use SQL
  Any valid PL/I variable name can be used for a host variable and is subject to the following restrictions.
• Statement labels in PL/I applications that use SQL
  All executable SQL statements, like PL/I statements, can have a label prefix.
• WHENEVER Statement in PL/I applications that use SQL
  The target for the GOTO clause in an SQL WHENEVER statement must be a label in the PL/I source code and must be within the scope of any SQL statements affected by the WHENEVER statement.
