Basic %L Dynamic Extraction Parameters

The basic dynamic extraction parameter format is

%LlnCcn %

where

• % represents the Special Character symbol specified in the SP CHAR field. This symbol appears at the beginning and end of the parameter.

Note: For this exercise, you are using the % character as the actual Special Character symbol, but it can be a symbol of your choice other than %.

• Lln specifies the report line from which you want to extract the string. ln represents the line number.
• Ccn specifies the first column of the string that you want to extract. cn represents the column number.

The ending % symbol may be placed any distance from the rest of the parameter. The number of columns from the beginning % symbol through the ending % symbol of a dynamic extraction parameter defines the number of columns extracted from the header line.

The first character of the extracted information appears in the same column number containing the beginning % symbol in the parameter.

For example, the dynamic extraction parameter format DTE: %L1C10 % resolves as follows:

• The special character is %.
• The extract is taken from the 1st report line, beginning with the 10th character.
• The length of the extract is 8 columns (the column range of the beginning % and ending % is 8).
• If the value beginning with the 10th character of the 1st report line is 05.05.00, the overlay line inserted in the report displays:
  DTE: 05.05.00

Dynamic extraction parameters for this exercise can now be defined in the overlay line.

1. Fill in the overlay line as follows (using the column numbering line as a guide).

   The dynamic extraction parameters you filled in produce the results described in the following table:

   Table 10 Example Dynamic Extraction Parameters

   Parameter	Description
   %L6C16%	Copies the value beginning on Line 6, Column 16. The copied string is the length of the parameter from the beginning % to the ending % (7 characters).
   %L6C38%	Copies the value beginning on Line 6, Column 38. The copied string is 7 characters in length.
   %L1C10 %	Copies the value beginning on Line 1, Column 10. The copied string is 8 characters in length.
   %L2C10 %	Copies the value beginning on Line 2, Column 10. The copied string is 8 characters in length.

2. Press the QUICKVIEW key (PF04/PF16) to display the Report Viewing screen, including the inserted line.
