INCLUDE can be used to perform arithmetic tests during sorting.


Syntax:

INCLUDE COND=(Field1 starting position, Field1 Length, Field1 format,
		 Relational Operator,alphanumeric_char)

Let’s discuss in detail.


nameDescription
Field1 starting positionStarting position of field1 to be compared
Field1 LengthLength of the field1 to be compared
Field1 format_typeSpecifies the format of the field1.
Use BI for Alphanumeric tests
Relation operatorRelational operators like GT, EQ, NE, LT etc,.

EQ 		Equal to
NE 		Not equal to
GT 		Greater than
GE 		Greater than or equal to
LT 		Less than
LE 		Less than or equal to
alphanumeric_charSpecifies the alphanumeric character type
The set of alphanumeric characters are provided below:
UC: Uppercase characters (A-Z)
LC: Lowercase characters (a-z)
MC: Mixed case characters (A-Z, a-z)
UN: Uppercase and numeric characters (A-Z, 0-9)
LN: Lowercase and numeric characters (a-z, 0-9)
MN: Mixed case and numeric characters (A-Z, a-z, 0-9)

Example:

From the below data, filter the records having the ID is alphanumeric and only numeric. The ID starts from 1st and ends at 5th column in the file.

Explaining Solution:

  1. As a first step, need to get the position of the ID in the file.
  2. The names starting from 1st position and ends at 5th position as per the input record layout provided. So the length of ID field is 5.
  3. As a Second step, need to get the type of the ID.
  4. From the Input record layout declaration, ID field is alpha-numeric. For alpha-numeric test, use BI instead of the actual field type.
  5. Lastly, the job requirement is to filter the data with the ID having alphanumeric and only numeric. So the keyword MN should use to match the condition.
  6. The INCLUDE condition for the above requirement with all the data gathered is

  7. INCLUDE COND=(1,05,BI,EQ,MN) 

  8. The above condition specifies that include the records where the ID having alphanumeric and only numeric.
  9. The output would have the records where the IDs are alphanumeric and only numeric at first 5 positions.
