Length May be from 1 to 9989 bytes long.

If an ASCII fixed-record-length translation is to be performed, specify *FILE to produce the desired file. If not translating to ASCII fixed-length records, any record length may be specified that could allow for better performance by buffering the data.

FLDSEL Allows the transfer of up to 25 user-specified fields from the host to the micro. For each field to be transferred to the micro, specify the following set of parameters: Field Name, Key Field, Ascending or Descending Order.

See Chapter 9, Advanced ETU Features, for examples of using field selection.

NOTE: Field selection can be used only with externally described files.

Field Name The name of the field to be transferred. The default, *ALL, transfers all the fields in the file. To transfer multiple fields, enter the name of each field to be transferred. Enter a plus sign () and press ENTER to display multiple prompts.

Key Field Sets the sort order of the records in the file after the file is transferred to the micro. The default, *NONE, does not re-sort the records, but leaves them in sequential order.

Valid Key Field values are *KEY1, *KEY2, *KEY3, up to *KEY25. For the field with the highest sort priority, enter *KEY1.

Ascending or Descending Specifies how records are sorted based on the key field value. Enter *ASC to sort records in ascending order and *DES in descending order

RECSEL Allows the transfer of user-specified records to the micro. The records that are transferred are selected based on the test cases you supply in the following parameters:

Relationship, Field to be Tested, Relational Operator, and Comparison Value.

You may create up to 15 test cases. To display multiple prompts, enter a plus sign () and press ENTER.

An example of a test case might be: if the value in the TOTAL field is greater than 1000, then transfer the record. In this example, 'if' is the relationship, 'TOTAL' is the field to be tested, 'greater than' is the relational operator, and '1000' is the comparison value.

NOTE: Record selection can be used only with externally described files.

Relationship Relates one test case to another. The first test case must use *IF. The default, *NONE, transfers
