The DQSCHEME Procedure

APPLY Statement

Applies a scheme to transform the values of a single variable.

APPLY LOCALE=<locale-name>
MATCHDEF=<match-definition>
MODE=PHRASE|ELEMENT
SCHEME=<scheme-name>
SCHEME_LOOKUP=EXACT|IGNORE_CASE |USE_MATCHDEF
SENSITIVITY=<sensitivity-level>
VAR=<variable-name>;

Options

LOCALE=locale-name

specifies the name of the match definition, in the specified locales, that is used to create match codes running the application of the scheme.

MATCH-DEFINITION=match-definition

specifies the name of the match definition, in the specified locales, that is used to create match codes running the application of the scheme.

MODE=ELEMENT | PHRASE

specifies a mode of scheme application. This information is stored in the scheme as metadata, which specifies a default mode when the scheme is applied. The default mode is superseded by a mode in the APPLY statement, or in the DQSCHEMEAPPLY function or CALL routine. See Applying Schemes.

ELEMENT: specifies that each element in each value of the input character variable is compared to the data values in the scheme. When SCHEME_LOOKUP=USE_MATCHDEF, the match code for each element is compared to match codes generated for each element, in each DATA variable value in the scheme.
PHRASE: this default value specifies that the entirety of each value of the input character variable is compared to the data values in the scheme. When SCHEME_LOOKUP=USE_MATCHDEF, the match code for the entire input value is compared to match codes that are generated for each data value in the scheme.

SCHEME=scheme-name

identifies the scheme to apply to the input data set. In all the operating environments other than z/OS, schemes using BFD format are identified by specifying a fileref or a fully qualified name that ends in .sch.bfd

SCHEME_LOOKUP=EXACT | IGNORE_CASE | USE_MATCHDEF

specifies the method of applying the scheme to the data values of the input variable.

SENSITIVITY=sensitivity-level

defines the amount of information in the resulting match codes.

VAR=variable-name

specifies the name of the variable that is analyzed and transformed.
