01 VAR2 PIC X(100).
EXEC SQL END DECLARE SECTION END-EXEC.
A declare section must end with the Embedded SQL statement end declare section.
A source file can have any number of declare sections.
declare sections can be placed anywhere that variables can be declared. The declare section that declares a variable must precede any statement that references the variable.
Variable declarations in a declare section must conform to the rules of the host language.
Nested structures are valid in a declare section; arrays of structures are not.
A declare section can contain any number of Embedded SQL include statements.
When processing Embedded SQL include statements within a declare section, the Embedded SQL precompiler treats the contents of the included file as though had been entered directly into the file being precompiled.
exec sql include "filename"
