Re: ASCII Spool file to DB file or Stream File

My personal favorite to read a user space is to retrieve a pointer to the 
user space using the QUSPTRUS api.  Then I can base a datastructure on 
that pointer.  When I want to read the next group of data, I simply add 
the number to the pointer.  Quite fast.

The alternative is reading the user space directly with the QUSRTVUS api. 
QUSPTRUS is cleaner code, and performs better.
If IBM decided to drop the ADD op code or the + sign in an eval statement 
and decided that you needed to call an api passing it 4 parameters: factor 
1, factor 2, result, error data structure; would that make you upset? 
That's about how pointless QUSRTVUS is once you understand how simple 
QUSPTRUS is.

The only applicable use of QUSRTVUS over QUSPTRUS is if you are a software 
vendor and your user space is not in QTEMP.  Because if your customer 
modifies system value QALWUSRDMN you cannot retrieve a pointer to a user 
space that is in a library that is not in the user domain, but is in the 
system domain.
