Hi Guys,
I have a File(VB) of record length 200.Most of the records in the file have data upto 150bytes. When i try to read the content of one such record at 170th Byte, the program is trying to read data from the next record instead of returning me a blank value.
Could someone help me with this. |

how about:
SELECT
FD
I/O instructions
working-storage definition of record if using WORK-AREA option. |

You do not answer my question.
READ verd in COBOL does a sequential read, one record per read. Unless you are using reference modifications I don't happen to understand how "170th Byte" was referenced.
Please show the "code" you are using which makes this

happen. Unless you code such an instruction, program does not try anything by itself. |

In addition to what Dick asked for, also post the COBOL statement(s) you are using to do this:

In your FD -
Code: |
RECORD IS VARYING IN SIZE FROM "smallest-length" CHARACTERS TO "largest-length" CHARACTERS DEPENDING ON WS-INPUT-LGTH. |
In WS (must be unsigned) -
Code: |
03 WS-INPUT-LGTH PIC 9(08) COMP.
|
This was introduced with VS/COBOL II. |

I'm eager to know what process was used to achieve this? |

probably by copying to a FB file of maximum length,
and back to a <pseudo(*)> VB,
(*) the file might have been defined as VB but all the records are of the same maximum length
wasting dasd space and having garbage in the unused part of the record
rant on
I wish that organizations would give proper training,
and provide code snippets to be used as samples for the most common tasks,
it seldom happens,
from the general tone of the questions in theseforums
looks like we are dealing with samples of the worst organizations around,
poor training, poor documentation, poor support,
above all poor cooperation between team members
in one concept poor management

Only if the guy at the next desk had any better experience. . . .
Time was, someone completely underqualified was a rarity in an IT office. Now there are places that have very few of even averge qualification. . . .
I also see no improvement any time soon. . .
