I have downloaded a data set that is in 3 parts, all in Excel.  Files 2

transferred the data with names to Stata, but the labels are perplexing.
 Here is  the format of the Excel spreadsheet with the variable names
and labels:

Column A    Column B       Column C    Column D   Column E
varname     varlabel          divider        varname     varlabel

Columns A&B are for data set 2 and C & D for data set 3 (though this is
no problem--I can copy them into one column since the cases are

Is there a way to transfer the variable labels without doing a lot of
typing.  Stata Technical Support suggested putting each variable label
into a do-file with quotation marks around each label (which I would
have to type in by hand) and then pasting:

label var varname "varlabel" for each variable.

Does anyone have a more expeditous (and less tedious) way of doing this


Yes. You can create the necessary do-files in Stata, using its string 
functions, especially concatenation.  Get the Excel spreadsheet into Stata via 
a tab-delimited or comma-delimited text file, or via ODBC or Stat/Transfer.  
Then insert the quotation marks around the variable labels.  An ASCII quotation 
mark is -char(34)-.  Then use concatenation to create a new variable that 
contains the command, append an "exit" (Stata likes "exit" at the end of its do-
files) and, finally, -outsheet- the column containing the concatentated string 
command into a text do-file, without variable names and without quotation 
marks.  I've illustrated the technique below in a do-file.  The first several 
lines are just to create a set of variables that represent an Excel spreadsheet 
patterned after the one you describe.  (Careful--the e-mail message and 
serverlist software might wrap the long datalines in the dummy spreadsheet data

// have already entered three lines of data
* The technique begins here
replace ColumnB = char(34) + ColumnB + char(34)
replace ColumnE = char(34) + ColumnE + char(34)
generate str ColumnA1 = "label variable " + ColumnA + " " + ColumnB
generate str ColumnD1 = "label variable " + ColumnD + " " + ColumnE
set obs `=r(N) + 1'
replace ColumnA1 = "exit" in l
replace ColumnD1 = "exit" in l
outsheet ColumnA1 using a:/, noquote nonames
outsheet ColumnD1 using a:/, noquote nonames
