Create File with specific Length
We have utility running on Unix which generates Files with records greater than 32760 , (max supported by Mainframe) .Our requirement is to transfer is file to Mainframe .When we ftp the in binary format it automatically wraps it up..so we are good there...
But now we need to zip and send the file , In such case the wraping doesn't happen and the data gets truncated while unzipping.

So is there a way to unzip without truncating data (We use pkzip on mainframe)
Is there a way to define the length of a File in Unix??our utility can wrap the output up..

Don't know about the mainframe, but have you checked out the fold utility on unix? See Man Page for fold (POSIX Section 1) - The UNIX and Linux Forums . You could use fold on your file before zipping it.

The data is in binary and inclued images , so if we fold by words still the length exceeds..if we do it by bytes, data doesn't get structured properly and gives errors down the line...
