The ASSIGN and DROP Verbs

Working With Mapping Services

The following examples use the MDO operand to specify MDO variables:

ASSIGN MDO=&abcdef. MAP=$SEC

ASSIGN MDO=&XYZ_1.

ASSIGN MDO=&MY_VAR. FROM MDO=&$INT.

EMSALERT MDO=&my_ems.

FILE ADD ID=INPUT_1 MDO=&record.

FILE GET ID=FILE1 MDO=&file_rec.

SECCALL UPDATE USERID=NNMABC MDO=&ums_record.

The MAP Operand

The MAP operand is used by some verbs to specify the name of the map used to

analyze data in an MDO variable. The syntax of the MAP operand is:

MAP=

map-name

specifies the name of the map you want Mapping Services to use to interpret the

data in an MDO variable. The map name is usually one of $MSG, $NCL, $SEC, or

$SPI.

The following examples use the MAP operand to specify the name of a map:

ASSIGN MDO=&abcdef. MAP=$SEC

ASSIGN MDO=&message. MAP=$MSG

The ASSIGN and

DROP Verbs

You can use the ASSIGN and DROP verbs to work with MDO variables. The ASSIGN

verb has four syntax formats. You can use two of these syntax formats to work with

MDO variables:

Format 1 of the ASSIGN verb allows you to manipulate multiple variables,

including MDO variables, in a single operation.

Note This section discusses format 1 of the ASSIGN verb in relation to MDO variables only. Refer to the

discussion on verb syntax and variable access methods in the NonStop NET/MASTER NCL Reference

Manual for a discussion of format 1 of the ASSIGN verb in relation to ordinary variables.

Format 2 of the ASSIGN verb allows you to obtain information about MDO

variables and maps.

Note Format 2 of the ASSIGN verb is used to obtain information about variables, not to assign values to

variables.

The DROP verb has one syntax format and is used to delete (drop) MDO variables.
