[SHARING] -RUN

My understanding of -RUN is that it forces the execution of stacked FOCUS commands. The focexecs I'm modifying have -RUN after Dialogue Manager commands.

The other programmer here was adamant that this is to make the Dialogue Manager commands work properly.

For example:

 
TABLE FILE...
END
-RUN
-READ ...
-SET ...
-RUN


I would think the 2nd -RUN is useless, yet the other programmer thinks it does something. Has anyone heard of using -RUN to force any Dialog Manager command to execute properly?

Thank you,

John

Some people seem to believe -RUN works for some Dialog Manager commands - I don't think that's true.

I only use it for non-Dialog Manager WebFOCUS code.

I'm agreeing with Francis (and apparently you too.) Any DM command that would have been encountered before the -RUN would be executed as soon as it was parsed. The official documentation says that the -RUN forces immediate execution of all FOCUS commands placed on the FOCSTACK. DM Commands are never placed on the FOCSTACK, so a -RUN would never have any effect on the order or timing of their execution.

Darin

I agree with Francis and Darin. I don't even like a -RUN at the end of a focexec. But then I'm a minimalist.

I agree with Francis, Darin, and Ginny. However, I do (sometimes) and have seen others use the -RUN at any "Logical break point", for readability more then functionality. The second -RUN in the initial post is useless.

I agree with Francis, Darin, and Ginny. I disagree with Ginny about the minimalist approach. I stick a -RUN after every set of JOINs, FILEDEFs and after every END statement. I accompany the -RUN with a check of &FOCERRNUM and a GOTO if there is an error. Why run through hundreds of lines of code if there is an error at the very top?

-RUN can be used to close files: 

CMS FI FOO DISK FOO DATA A               
-RUN                                     
-WRITE FOO HELLO                         
-WRITE FOO THERE                         
-RUN                                     
-READ FOO &VAL.5                         
-TYPE &VAL                               
-RUN                                     
-READ FOO &VAL.5                         
-TYPE &VAL                               
-RUN                                     
-TYPE THAT WAS WITH RUNS... NOW WITHOUT  
-*                                       
-READ FOO &VAL.5                         
-TYPE &VAL                               
-READ FOO &VAL.5                         
-TYPE &VAL                               
-RUN


Change the filedef to whatever is local to your machine and try the above code: -RUN causes FOO to close, and thus read and write from the start of the file.

I'd give extra points to Francis for the implementation of error checking... I use, as I'm sure many others use as well, "-INCLUDE ErrorCheck" routines that start with a -RUN and go on to error handling...

A follow-up question: Does the -RUN actually CLOSE the file? Or, does it reset the pointer back to the top-of-file? I understand that the end result is the relatively same as illustrated by Edward Wolfgram's code.

I've never seen this behaviour because I never use -RUN with Dialog Manager. Good example Mr. Wolfgram.

My code would look like:

FILEDEF FOO DISK FOO.FTM
-RUN
-*
-WRITE FOO HELLO
-WRITE FOO THERE
-CLOSE FOO
-*
-READ FOO &VAL.A5.
-REPEAT END_REP1 WHILE &IORETURN EQ 0;
-TYPE &VAL
-READ FOO &VAL.A5.
-END_REP1
-TYPE EOF FOO

Doug,
-RUN actually closes all open files, unless they have been opened in DM with the NOCLOSE option specified. These latter files will stay open and positioned.

Thanks Gamp,
This shows that -RUN does more then just executing the items in the stack. I don't recall seeing the -RUN / CLOSE in any documentation - that's not saying that it's not in there someplace.

Not documented as such

-RUN also closes files opened for -WRITE operations

And -WRITE has the same effect on a file opened for a -READ
unless you use the NOCLOSE option
