Only Second Range Specified
The following ranged-variable-specification specifies only the second range:
&[ variable ] *
and
RANGE ( start2 , end2 )
In this case, NCL generates or targets variable names that satisfy the second range.
Here are some examples:
What You Type Comment
DROP VARS &* RANGE=(5,6) Deletes &5 and &6.
DROP VARS=&A* RANGE=(10,15) Deletes &A10 through &A15.
Both Ranges Specified
The following ranged-variable-specification specifies both the first and
second range.
&[ variable ] * ( start1 , end1 )
and
RANGE [ = ] ( start2 , end2 )
In this case, NCL generates or targets variable names that satisfy the first range, if a
first range is provided. If a first range is not provided, it uses the second range. Here
are some examples:
What You Type Comment
INTREAD VARS (&A*(5,10),&B*)
RANGE=(20,30)
Generates &A5 through &A10 and &B20 through
&B30.
LOGREAD VARS=(&A*,&B*(1,10))
RANGE=(5,8)
Generates &A5 through &A8 and &B1 through
&B10.
Specifying Variable Length You can specify a variable name and indicate the maximum amount of data (in bytes)
that it can hold in a VARS list. This option affects how the data is stored in the
variables in the VARS list. Here is the component of the VARS list that you use to
specify a length-variable-specification :
&[ variable ] ( length )
