I've got a simple problem but haven't done this often enough to know what all the issues are. I wouldn't ask if I wasn't up against a deadline.

I need to read a string from a text file. The string is 20100130. It's the only thing in the file. I've done something similar ON TABLE

I'm sure there are extra things that must be done when reading a file from scratch, but I'm not sure what they are. I've read lots of posts this morning, so far, they provide examples of the READ right after a ON HOLD. I haven't found anything (not sure if it's different) that speaks to using an existing file.

ON TABLE TABLENAME
PRINT FIELD
HOLD AS TEMPNAME FORMAT ALPHA
END
-RUN
-READ TEMPNAME &TEMVAR.A8.


The above works just fine, this is the first time I've tried to read an existing file. Heres what I have so far:
APP FI MAXPOST DISK guidedbi/bi_max_post_date.txt

-READ MAXPOST &MAXDate.A8.
-? &MAX
-EXIT

I get this error message:
0 ERROR AT OR NEAR LINE 3 IN PROCEDURE ADHOCRQ FOCEXEC * (FOC339) DIALOGUE MANAGER -READ FAILED: CHECK FILEDEF OR ALLOCATION FOR: -READ MAXPOST &MAXDate.A8.

Any help would be appreciated.

Try adding -RUN right after APP FI ... You can then attempt to -READ from it.

Is "guidedbi" a defined application path in your environment?

-RUN worked. Thanks so much.

You may also try substituting FILEDEF for APP FI. I always use the former since it allows to map files not only to application paths under "approot" but also to any physical location.

This should have the same effect as APP FI:
FILEDEF MAXPOST DISK quidedbi/bi_max_post_date.txt


or, in case you need access to a file sitting "anywhere" that is neither a directory under approot nor a mapped directory:

FILEDEF MAXPOST DISK C:\DataFiles\bi_max_post_date.txt


Don't forget the -RUN statement right after the file mapping and before -READ.

Hope that helps!

Neftali, you can use the APP MAP command to map to alternate file locations.

Thanks Ginny! I use APP MAP in production reports when there is a need for accessing content outside the regular approot location, that is, until I manage to convince the WF administrator to map those locations directly in the global or user profiles in the Reporting Server.

For a "quick" solution and out of laziness I've taken the not-so-good practice of using FILEDEF to hard-wire the file location there.

You're point is very valid Ginny and using APP MAP should be the way to go for the sake of keeping code that is clean and most importantly maintainable.
