Hi Everyone.
Long Story short, I need to process an XML File in a cobol Program, which i've been reading about I can perform using the XML PARSE utility from enterprise cobol 6.3.
I don't have much experience working with Variable Length files, but our best guess is that the input file could be of variable length. I have a sample file which i want to test, which has the following Info screen
| Code: |
Data Set Name . . . . : TDES.XML.SPOT.TR
General Data Current Allocation
Management class . . : **None** Allocated blocks . : 5
Storage class . . . : **None** Allocated extents . : 1
Volume serial . . . : ABCXYZ
Device type . . . . : 3390
Data class . . . . . : **None**
Organization . . . : PS Current Utilization
Record format . . . : VB Used blocks . . . . : 1
Record length . . . : 10000 Used extents . . . : 1
Block size . . . . : 10004
1st extent blocks . : 5
Secondary blocks . : 0 Dates
Data set name type : Creation date . . . : 2021/10/27
Referenced date . . : 2021/10/27
Expiration date . . : ***None***
SMS Compressible . : NO |
This is an extract of the cobol code i have implemented for this task

And this is the error I'm getting while opening the file. File status 39. A mismatch on lengths that I'm not sure where it is.
| Code: |
********************************* TOP OF DATA **********************************OF DATA **********************************
IGZ0201W A file attribute mismatch was detected. File FENTRADA in program MIFD1113 had a record length of 10004 and

Any feedback or help would be appreciate it. |

| You need to allow for the 4 byte record descriptor word (RDW) which starts every variable length data set. Change 10000 in your program to 9996. |

Thanks a Lot Robert. It worked just fine. I'll need to check the documentation in depth but this fixes my current issue.
Cheers! |
