Numeric Host Variables

The syntax for numeric host variable declarations is as follows:

DECLARE var-name-spec {BINARY | DECIMAL} scale-spec align-scope-storage ;

where:

`var-name-spec`	is {`variable-name` \| `(variable-name`, ...) }
`scale-spec`	is {FIXED [(`precision` [,`scale`])] \| FLOAT [(`precision`)]}
`align-scope-storage`	is any set of PL/I alignment, scope, or storage class attributes

Note:

BINARY | DECIMAL and FIXED | FLOAT can be specified in either order.
The precision and scale attributes can follow BINARY | DECIMAL instead of FIXED | FLOAT.
A value for scale can be specified only for DECIMAL FIXED.
DCL, BIN, and DEC are accepted as abbreviations for DECLARE, BINARY, and DECIMAL, respectively.
