[SOLVED] Calling a procedure for each record in TABLE FILE
I have a reusable procedure that I want to call from a master procedure. The master procedure has a TABLE FILE command. I want to call the reusable procedure for each record in the table in the master procedure and pass values in the current record as parameters to the reusable procedure. Is that possible?This message has been edited. Last edited by: <Kathryn Henning>,

Yes, but I am not aware of any default functionality to do this (unless the process can be done in a define function).
You will need to hold the records, then use Dialog Manager to read the record as amper variable that can then be picked up by the sub procedure.
without knowing what your process actually its difficult to suggest much more.

Once you hold your file from the master procedure you can establish a loop to read each value or set of values into parameters, do whatever you are going to do with them and return to repeat the loop until you get through all of the held records.

Thank you both for your answers. I was hoping that I would be able to do it directly inside a TABLE FILE or DEFINE FILE, via calling a function or something like that. It sounds like that's not possible.

It can be done without resorting to a dialog manager loop. Something like this:
FILEDEF DRIVER DISK driver.fex
DEFINF FILE HOLD
CMD/A1000 = . . . ;
END
TABLE FILE HOLD
PRINT CMD
ON TABLE SAVE AS DRIVER
END
-RUN
-INCLUDE driver.fex
CMD would contain the EX command, to call the fex and pass the arguments. It would be defined be a catenation of 'EX fexname ' 'parmname=' character representation of value ',' . . .

How complex is the reusable procedure ?
What is it doing ?
Could you enhance that procedure to accept a hold file and process it, so the loop is self contained.

JC,
What do you call a "reusable procedure"? In what language is it written? 3G? FOCUS? And what does the reusable procedure do?

Sorry for not following up on this post after such a long time. The solution suggested by j-gross works for me. Thank you all for your inputs.
