The syntax for character host variable declarations is as follows:
DECLARE var-name-spec CHARACTER [(length)] [VARYING] align-scope-storage ;
where:
|
var-name-spec
|
is {variable-name | (variable-name, ...) }
|
| align-scope-storage
|
is any set of PL/I alignment, scope, or storage class attributes |
Note:
- For non-varying character host variables, length must be a constant no greater than the maximum length for SQL CHAR data.
- For varying-length character host variables, length must be a constant greater than the maximum length for SQL LONG VARCHAR
data.
- DCL, CHAR, and VAR are accepted as abbreviations for DECLARE, CHARACTER, and VARYING, respectively.
