N OF CASES

[Albert-Jan Roskam]

This week I found out that N OF CASES now (v20) requires an EXECUTE, whereas before (v14) it took effect immedately.
That's also what the CSR still says. I often do N OF CASES 1000 to debug code, but it now also needs an EXE.

Is that intentional?

I'm not following.  All N OF CASES does is to permanently limit the number of cases that will be read, so this can only take effect on the next data pass.  N OF CASES does not trigger a data pass.  But there would be no need for an EXECUTE except for something like SHOW N run before the next data pass.

 CASES does
 not trigger a data pass.  But there would be no need

 except for something like SHOW N run before the next data
 pass.

--> From the CSR: "N OF CASES takes effect as soon as it is encountered in the command sequence."
 And on p 44: "Other Commands That Take Effect Immediately"... N OF CASES... *)

That corresponds wiith my idea that this command interferes with a data pass, e.g. GET FILE starts reading a file, but it stops at a given record after encountering N OF CASES.

IIRC, I did something like this (I am not 100 % sure):

GET FILE...
N OF CASES 1000.
SORT CASES BY id. /* was supposed to be only a 1000 cases!.
MATCH FILES /FILE = * /TABLE = "..." /BY id.

After the sort you will have no more than 1000 cases.  The rest will be gone.
