Hi.
I have a I/P & O/P VB File and the length of the file is 10504 in JCL including 4 bytes.
Each record in this file is of different length and i don't know the actual length's for each record.
Say record 1 is 100 bytes and then remaining 10400 bytes is having Nulls.
Say record 2 is 2000 bytes and then remaining 8500 bytes is having Nulls.
Say record 3 is 2000 bytes and then remaining 8500 bytes is having Nulls.
My problem is to convert only Trailing Nulls to Spaces.
I would appreciate if anyone responds to this posting.
Thanks,
Srini |

What sort product do you have?
What programming languages do you have?
Can you use REXX?
In your example, are you trying to convert the 100 byte VB record and the two 2000 byte VB records to a FB format with a lrecl of 10504 bytes with spaces for padding? |

we use sort,syncsort,icetool in our shop and rexxtool is not allowed.
i am converting VB to VB same length.
When i did conversion , i got nulls as Trailing character's for every record after the actual length of each record .
Each record length varies based on data present in each record.
Thanks |

VB to VB conversion is a kind of useless process
Using VB records is a way of saving dasd space by wring to dasd only the data available and needed
do You realize that when converting VB to FB You might waste a tremendous amount of space
for example 1 track will hold approximately 540 100bytes records
if You convert these record to a fixed format with a record length of 10550
only 4 records will fit on a track and the space used to hold the 540 records will be 135 tracks r 9 cylinders..... meditate |

When you displayed the record you saw trailing nulls to the max lrecl of 10504? |

Hello,
How do you define "nulls"?
There is no NULL Value concept in a qsam file - whether it is fixed or variable length. . . |

| And if you EDIT the file - YES you will see blanks X'40' right up until the end of the record length. |

Hi,
and if you browse the file and put HEX ON you will see where the data ends.
