Can I specify an if/then statement in power_cmd_init?

[Ariel Linden]

Hi All,

I am writing a power command using power_usermethod. I would like to have the power_cmd_name_init program change the title, depending on whether an option was specified in the power_cmd_name program. Something like this completely contrived example:

capture program drop power_cmd_whatever_init
program power_cmd_whatever_init, sclass
        version 11
       if "`level'" == "" {
           sreturn local pss_title " for a test of upper level"
     }
    else {
       sreturn local pss_title " for a test of lower level"
    }

The local "`level'" would be in the power_usermethod command. I am not sure if I can use a passthrough, or how else to do this. The help file does not discuss this issue.

Thanks in advance!

Hi All,

I want to thank Kerry Kammire at StataCorp for providing the answer to this problem.

The option "level" is an option in the evaluator program "power_cmd_whatever". This option is passed to the _init program where it is also evaluated:

capture program drop power_cmd_whatever_init
program power_cmd_whatever_init, sclass
   version 11
   syntax, [level] *

   if "`level'" == "" {
      sreturn local pss_title " for a test of upper level"
   }
   else {
      sreturn local pss_title " for a test of lower level"
   }
end
