RE: work files in qtemp

[Alan Campin <Alan.Campin@xxxxxxx>]

Method is simple enough. 

1. Create a template file on your library list for the job.
2. Use template file to compile program.  
3. Have a CL Driver do a Delete file to destroy it if it already there.
4. Do a CRTDUPOBJ to QTEMP.
5. Issue override to copy in QTEMP. 
6. Call program.
7. Delete override.
8. Delete workfile in QTEMP.

Someone, also, suggested user indexes. Only disadvantage is additional 
complexity. Have to write to the API's.

Also, User Spaces work very well depending on how you are going to use the 
data. In other words, does it need to be sorted or just stored. If just stored 
and retrieved, User Space are extremely fast and simple to use. Just get a 
pointer into a user space and map it to a multiple occurrence data structure. 
The user space and the data structure are now the same. When you occur, you 
walk through the user space. You have, in effect, up to 16MB of virtual storage 
that is automatically managed for you. You can, also, sort the user space or do 
lookups using QSORT or BSEARCH. 

I have user space API's I could send you if you are interested. Code is, also, 
available through this forum but I hate to include functions that should be in 
a service program in a program. Writing the same code, again and again just 
drives me crazy. On my soap box again.

Subject: work files in qtemp


I have been working on a program that will reuqire me to use some sort of 
temporary hold file, a friend suggested that I use a work file in qtemp for 
the processing of the data...however, I have never used work files before, 
let alone in qtemp.

Should I just create the file in my library and then copy it to the qtemp 
directory and then process the data deleting the file once I am done? Any 
other suggestions would be appreciated.
