Lance,
Try something like this:

	forv i=1/3 {
		 drawnorm name`i', m(mean_var`i') sd(sd_var`i') 
	}

You'll run into problems, though, if your data actually includes the
variable names you list since there isn't a sd_var1.

standard deviations

Statalist members,

I'm trying to get Stata to generate a distribution of data from variables in
my data set.

My appended data looks like this
mean_var1=90
standard_deviation_var1=5
mean_var2=100
sd_var2=10
mean var3=110
sd_var3=15
and so on

I'm need a loop that will take my variables and create the distributions for
me.
I've been using the drawnorm command
     drawnorm name1, m(mean_var1) sd(sd_var1) but I can't get it to
recognize more than 1 variable at a time

I want it to perform the distribution command for each pair of my variables.
I.e. (m_var1, sd_var1), (m_var2, sd_var2) , (m_var3, sd_var3)

Thanks for your consideration,

Lance
