The ascending key requirements of successive record key values has been violated, or, the prime record key value has been changed by a COBOL program between successful execution of a READ statement and execution of the next REWRITE statement for that file. 22 Indexed and relative files only. In...
The following example shows how you can use the file status code and theINVALID KEYphrase to determine more specifically why an input or output statement failed. Assume that you have a file that contains main customer records and you need to update some of these records with information from a...
This example contains two COBOL programs. The first is a demonstration program that calls the COBOL conversion routine and then writes to the file of Status Codes. The COBOL conversion routine does the actual conversion from a two-byte field to a four byte, numeric value with a one-line des...
In this example the mapper file is named STFILEORA. The file processes only one file named PJ01AAA.SS.VSAM.CUSTOMER that is migrated to an Oracle table using the convert option. The ODCSF0B.cpy copy file used to describe the file is one of the source copy files....

Restriction:The data item referenced in theFILE STATUSclause cannot be variably located; for example, it cannot follow a variable-length table. Related tasks Using file status keys Related references FILE STATUS clause(COBOL for Linux® on x86 Language Reference)...
Each configuration could be related to a different application for example, or a set of files required for tests.File descriptions and managing files with the same structureFor each candidate file for migration, its structure should be described in Cobol format. This description is used in a ...
This example uses a suite of COBOL programs and BMS map sets to display a screen to prompt a user for a file status code. When the user enters the code a brief description of what caused the condition will be displayed. The transaction identifier (or Tran ID) for this menu option is"...
We are sending file from Mainframe to ADLS through FTP in binary mode. The binary data we are reading through Cobrix and creating parquet file out of it. The FB files are working like a charm. spark.read.format("cobol").option("copybook", "/data/example1/test3_copybook.cob").load("...
