DROP
Verbs
3–48 106126 Tandem Computers Incorporated
DROP The DROP verb deletes (drops) multiple variables in a single operation. When you use
this verb, not only the content, but also the names of variables cease to exist within the
current scope of the NCL procedure. The DROP verb can delete any variable that has
attached attributes, such as ERROR or MODFLD attributes that are attached to
variables by PANEL statements.
You can delete MDO and global variables using the DROP verb. You cannot delete
system variables (those variables which begin with the &SYS. stem).
DROP { ARGS [ RANGE=( start , end ) ] |
VARS={ input-vars-list | variable * }
[ RANGE=( start , end ) | GENERIC ] }
ARGS
specifies a range of variables. See “Frequently Occurring Operands,” at the
beginning of this section, for more information.
RANGE=( start , end )
determines the range of variables specified by the ARGS operand. See
“Frequently Occurring Operands,” at the beginning of this section, for more
information.
VARS
input-vars-list
contains a list of variables to be deleted. Multiple variables must be enclosed
in parentheses and separated by commas.
variable*
specifies a set of variables. See “Frequently Occurring Operands,” at the
beginning of this section, for more information.
RANGE=( start , end )
determines the range of variables specified by the VARS operand. See
“Frequently Occurring Operands,” at the beginning of this section, for more
information.
GENERIC
specifies that the VARS= variable* operand acts as a modifier that you can
use to select a range of currently existing variables with any alphanumeric
suffix.
