Loop through reports and extract title

doctorfizz — Wed, 31 Jul 2024 16:08:11 GMT

Hello,

I am trying to loop through all reports generated from an ANOVA-oneway. I create a list of the reports anova_list.

If I manually try to extract the title from a report with the following syntaxt

curr_anova = anova_list[1]

report_title = curr_anova << report << get title("string")

the output is what I expect - some variation of: Oneway Analysis of Y by X by1=by1val by2=by2val ...

But when I try to do this in a loop

for(i = 1, i<= n items(anova_list), i++,

curr_anova = anova_list[i]

report_title = curr_anova << report << get title("string")

)

the output of report_title is DisplayBox[OutlineBox].

Am I making an oversight on the syntax? I have tried different combinations of evals to see if the output change, to no avail.

Try changing

report_title = curr_anova << report << get  title("string")

to (the brackets being the most important)

report_title = (curr_anova << report) << get  title;

jthi,

thanks for the suggestion. This indeed does the trick!

May I ask why this is different? What does the containment with parenthesis do?

Your original version created a 'message cascade:"

result = obj << message 1 << message 2;

The result is from the succession of messages to the same object. Using the parentheses sends the second message to the result of sending the first message.
