I have coded a cobol pgm of updating a flat file of variable length.
The pgm works fine for flat files with SMS-compressible-NO option.
But it creates a pblm fr the file with SMS-compressible-YES option.
It gives a error that FILE-STATUS is 90 i.e. open error.
Block contains 0.
Record varying in length from 1 to 4092.
In my jcl.
sysut1 is the input file name.
sysut2 is the op file with the attributes that are same of the input file.
Can you please tell on what basis does the system gives the attributes as sms compressible yes or no.
Is it on the basis of the reocords it contain?
I just copied ten records of that file then it showed me sms compressible yes and the pgm worked.
But whe i tried to copy the whole big file what tracks and cylinders or any option should i give so that it gives sms compressible no.
Try to pls emphasize on sms compressiblitys creteria.
