st: Problems that seem to be the result of a "long command line" in a do file

["Hoogendoorn, Adriaan" <A.Hoogendoorn@ggzingeest.nl>]

Dear Statalist,

I encounter some problems that seem to be the result of a "long command line" in a do file, even though I broke the long command line up into several parts over several lines (see below).
The problem may be the result of my bad knowledge of Stata on this point.
I encounter the problem in a call to the 'confa' command in Stanislav Kolenikov's package that does Confirmatory Factor Analysis (package st0169 from http://www.stata-journal.com/software/sj9-3).

The call:

confa (list_ae: ru001ae01 ru002ae02 ru003ae03 da001ae01 da002ae02    ///
                da003ae03 vo001ae01 vo002ae02 vo003ae03 vo004ae04 )  ///
      (list_ep: ru005ep01 ru006ep02 ru007ep03 ru008ep04 ru009ep05    ///
                da005ep01 da006ep02 da007ep03 vo005ep01 vo007ep03 )  ///
      (list_et: ru011et01 ru012et02 ru013et03 ru014et04 da011et01    ///
                da013et03 da014et04 vo011et01 vo012et02 vo013et03 )  ///
      , from(smart) iterate(50)

results into the error message "da0 ambigous abbreviation", while the call:

confa (list_ae: ru001ae01 ru002ae02 ru003ae03 da001ae01 da002ae02     ///
                da003ae03 vo001ae01 vo002ae02 vo003ae03 vo004ae04 )   ///
      (list_ep: ru005ep01 ru006ep02 ru007ep03 ru008ep04 ru009ep05     ///
             da005ep01 da006ep02 da007ep03 vo005ep01 vo007ep03 )   ///
   (list_et: ru011et01 ru012et02 ru013et03 ru014et04 ), from(smart) iterate(50)

- which is identical to the first call, except that 'list_et' consists of four instead of
ten variables - works fine.

Do you know of a way I can run the first command?
I could use shorter variable names, but I am hoping for a more elegant solution.

Your help is very welcome.

Kind regards,
