Dear Statalist, 

I have some 20 variable names in a local macro, called "vars" , and I want 
to know exactly how many there are. Why doesn't this work?

. di wordcount("`vars'")
12

Or even this?

. #delim ;
. di wordcount("f4_latepreg_sample f4_date_late_control_visit 
f4_final_latepreg_sample f5_marital_status f5_country_of_birth 
f5_main_ethnicity f5_oth_ethnicity f5_ethnicity_custcentiles 
f5_immigration_hx f5_partcpt_migration_yrs f5_partnr_migration 
f5_yrs_schooling f5_tertiary_edu f5_oth_tertiary_edu f5_job_situation 
f5_mat_occupation f5_major_grp f5_socioeconomic_index f5_living_situation 
f5_children_in_house f5_current_accomod f5_type_accomod 
f5_partcpt_partnr_income f5_individuals_support_dollar f5_type_maternity_care")
;
12
.#delim cp

This doesn't work either, but I think I know why.
 . di wordcount(`vars')
invalid syntax
r(198);

I can't see this behaviour mentioned in the manuals.
Is it a bug; or an obscure "feature", whose advantages I am blind to?
Is there any way of stopping Stata truncating the list before counting the words, 
and why should I have to?

I am using Stata version 11.2, on a Windows platform.

Many thanks.
