John,

Although there are some things I'm not clear about, I'm not sure that you
need a macro. From your example code, it looks like your data are all in one
file with a strucure like this:

SchID SchName Grade v1 ... V345

You could sort by schid and grade and then
Split file by schid grade.
Frequencies ...
Ctables ...

Split file off.

What you don't get with split files is the changing title.

You could do this with a looping macro and there is an example of one, I
seem to recall, in the macro section of the syntax reference, which you
should have on the help menu. I don't know much about macros but others on
the list are macro stars.

I'd suggest that you check the split file command first.

Subject: [SPSS] Using a loop/vector to run a syntax file

I am a self-taught SPSS user, and have struggled with creating a loop
structure to run a syntax file that generates several custom tables in the
vanilla version of SPSS Statistics 19. After doing additional research, I
*think* the proper method to handle this issue is to place the reporting
syntax into a macro structure, and call that macro within a loop or vector
structure.

I need to run this syntax dozens of times, and would like to automate that
process. Ideally, I would like to send the school number and school name
into the macro, and have the macro search using the school number and add
the school name in the TITLE command. (The school number would be
substituted for "07621" in the filter condition of line 3 of the syntax, and
the school name would probably need to be CONCATed in the TITLE call on line
13 in place of Holt Central HS).

As an example, if I had three buildings:

ID   Name
123 First School
253 Second School
521 Third School

Then the macro call might look like !myreport schoolnum schoolname.

The reporting syntax follows:

>
> USE ALL.
> COMPUTE filter_$=(Building = "07621" AND (Grade<=12 OR Grade = 14)).
>  * COMPUTE filter_$=(OperatingDistrict = "33170" AND (Grade<=12 OR Grade =
14)).
> VALUE LABELS filter_$ 0 'Not Selected' 1 'Selected'.
> FORMATS filter_$ (f1.0).
> FILTER BY filter_$.
> EXECUTE.
>
> /**** Q1 - Total School Enrollment  ****/.
> /***** TABLE 1 ********/.
>
> TITLE Holt Central HS 2007-08 Pg. 4 - Student Enrollment by Subgroup.
> FREQUENCIES VARIABLES=EDFlag SWDFlag LEPFlag HomeFlag MigFlag

Am I headed in the right direction? How would I "step through" my school IDs
and school names for the repeated calls to the macro? In my old BASIC days,
it would be a simple DATA-READ pair within a FOR-NEXT loop, and I'd assign
the values to an array. I'd then use a second FOR-NEXT loop to step through
the elements of the ARRAY  as I called the subroutine. Unfortunately, my
BASIC experiences don't seem to have much application in the SPSS syntax
arena.

Unfortunately, I find the SPSS documentation to be far too comprehensive
(too many options and flags) to act as a good learning tool, and haven't
been able to find a tutorial online that addresses this type of process, or
that doesn't require far greater knowledge of the control structures than I
currently possess. Can anyone on the list offer some assistance, or point me
to a good beginning-intermediate resource for learning these types of
control structures? Thanks, in advance.

...and if this isn't the type of question that is appropriate for this list,
my apologies!
