-parmby- (like earlier versions of -statsby-) takes a command line (in quotes) as part of its input. If you are in the default Stata carriage-return-delimited mode defined by

#delim cr

(see -help delimit-), then you cannot split long quoted strings between lines, as Jamie is trying to do.

The solution I usually use is to do my programming in the non-standard semicolon-delimited mode defined by

#delim ;

which allows users to split quoted strings between lines, becuase commands are delimited by semicolons. As in:

parmby "regress
 mpg weight",
 list(,);

which works in my do-files (which start with -#delim ;-).

Jamie might like to use semicolon-delimited mode only with -parmby- and other special applications, which use very long quoted strings, and use carriage-return-delimited mode elsewhere. As in:

#delim ;
parmby "regress
 mpg weight",
 list(,);
#delim cr

An alternative possibility is to build the command in a local macro. As in:

local cmd `"regress"'
local cmd `"`cmd' mpg weight"'
parmby `"`cmd'"', list(,)

I hope this helps.

Best wishes

Roger

Dear Statalisters,

I'm using Stata/SE 10.1 for Windows. Born 10 Jun 2010. All files are up to date.

My query is about -parmby- (http://ideas.repec.org/c/boc/bocode/s352601.html).

The following command works fine.

parmby "xi: mlogit walkcat i.tertsoccoh i.sex*age  i.schrpV1  i.urbrur
if tousewalkcat0407V1,rrr vce(cluster pseudo) base(0)", by(qinc)
saving(Graph4/GSSocCapWalk04IncIntSoc, replace) eform for(estimate
min95 max95 %8.2e)

However, it's rather long. I'd like to break it over one or maybe two
lines. I tried this:

. ***Stratification models for graph of interaction in "GSSocCapWalk04IncIntSum"
.
. parmby "xi: mlogit walkcat i.tertsoccoh i.sex*age  i.schrpV1  i.urbrur ///
You must specify at least one of the four options:
list(), saving(), norestore, and fast.
If you specify list(), then the output variables specified are listed.
If you specify saving(), then the new data set is output to a disk file.
If you specify norestore and/or fast, then the new data set is created in the me
mory,
and any existing data set in the memory is destroyed.
For more details, see on-line help for parmby and parmest.
r(498);

I checked the on-line help, and the archives to see if this has come
up before but I couldn't find any references to it. Is -parmby-
different to other commands when it comes to breaking across multiple
lines?

Thanks for your consideration,

Jamie
