I usually have a bigger class of task or assignment, from which the individual information is pulled out. An example structure for renaming could be:

clear all

class Pair {
  string from
  string to
}

class Plan {
  array content
}

.renaming=.Plan.new
.tmp=.Pair.new

.renaming.content[1]=.tmp
.renaming.content[1].from="a1"
.renaming.content[1].to="b1"
.renaming.content[2]=.tmp
.renaming.content[2].from="a2"
.renaming.content[2].to="b2"
.renaming.content[3]=.tmp
.renaming.content[3].from="a3"
.renaming.content[3].to="b3"
.renaming.content[4]=.tmp
.renaming.content[4].from="a4"
.renaming.content[4].to="b4"

display "`.renaming.content[1].from'"
display "`.renaming.content[2].from'"
display "`.renaming.content[3].from'"
display "`.renaming.content[4].from'"

.third=.renaming.content[3]

display "`.third.from'"

It looks intimidating at first, but is actually very simple. The important part is that one can work explicitly with pairs of values (e.g. the use of .third).

Best, Sergiy Radyakin

Alan,

Thanks; this is much closer to what I had in mind, although with a lot of punctuation to keep track of. It's too bad that more attention is not paid to this feature in courses and here on Statalist. A good addition to the "toolbox"!

Regards,
Joe

John has the right idea. In this example it could be just

forval j = 1/4 {
scatter A`j' B`j' , name(`j')
}

I added a name() option: otherwise each plot just disappears as the next is drawn.

Hi everyone,

what if I wanted to generate a loop whose argument consisted of 3 different varlists, in order to estimate, for instance, 3 different probit models?
I though I could generate three local macros and then estimate, but I am wrong, e.g.,

local one var1 2 vr3 //fictional names
local two var2 ar6 r9
local three r4 ar3 ar8
#delimit;
foreach x of local one two three {;
use data.dta, clear;
probit DV `x';
};

I searched through the forum, but failed to find a solution. I will appreciate feedback on this (apparently easy) issue.
