Hi as you specified we have five types of record formats

when u know exactly the length of record lay out then you
can specify fixed or fixed block.Then system will allocate
the fixed lenth for the record. when u enter data it takes
exactly fixed lenth as u specified, if u give data less
than the length specified also then system will allocate
the fixed lenth only . Memory will be wasted.

When you are not sure of record format i:e if u specify the
length of a record is x(156) , then record may be of 156
or it may be less than that.
more record length it wount accept,
same record lenth as specified accept ,
record which is of less than specified size accept.

here memory wount be wasted.System will allocate memory
based on record data u supply.

undefined format we usually use for load libs. we are not
sure how long the data will be. then we will specify
undefined.

when we use the FB we cant compress it,to free the unused
space ......
but in VB we can compress the PDS to free the unused space
in it ...
when we use U it is used for storing only executable files
.... that is the load module,what we get
when we compile the cobol program

Answer / mr.perfect

hi Vinothaaa , yours answers wrong.

FB -- We can compress , because i used the my cobol prgm in
this format, whenever space is not enough. i used to compress.
it is allowed me to do this.

U --unformat mode, the data will store in not human readbale
format.

I have a occurs for 100 times but it has executed 101 time what could be the reason?
