Have you looked at the manual and the "System-Defined File Fields"
Quote:
RECORD-LENGTH ? a two-byte binary field used for all file types to determine or establish the length of the current data record. For variable-length records, this field contains only the length of the record's data. That is, CA-Easytrieve/Plus automatically adjusts the field to account for the four-byte record-control-word and four-byte block-control-word. For variable-length files, assign the length of the record to the RECORD-LENGTH field before the PUT or WRITE statement is executed.
An example of creating a variable-Length SAM file with a value:
Code:
FILE CARDFILE CARD
FIELD 1 5 A
FILE OUTFILE VB(100 504)
FIELD 1 5 A
JOB INPUT CARDFILE NAME MYPROG
OUTFILE:RECORD-LENGTH = 5
PUT OUTFILE FROM CARDFILE
END
CARD1
CARD2
CARD3
CARD4
CARD5
And an example of creating a variable-Length SAM file with anaother record-length:
Code:
FILE INFILE VB(100 504)
FIELD 1 5 A
FILE OUTFILE VB(100 504)
FIELD 1 5 A
JOB INPUT INFILE NAME MYPROG
OUTFILE:RECORD-LENGTH = INFILE:RECORD-LENGTH
PUT OUTFILE FROM INFILE

Hello,

If your organization is licensed to use Easytrieve, you can get all of the documentation for free from Computer Associates(CA). It is available for download from the CA Support Site.
