Hi
Thanks very much for your help. However, permit me to restate my
problem. It is like this: If I do not specify "tempvar y`x'iqq
y`xless1'iqq;" within the loop as below, I get the error message that
"too few variables specified" which after using 'set trace on' and
'mat li' translates into "global macro $ge is not recognised" or
something like that. On the other hand, including it solves that
problem but introduces another - looping through encounters tempvar
again and yields the error message that the variable has already been
created.
I suppose, what I would like to know is whether tempvar and tempname
cannot be used in the way that I am trying to and if so, is there any
other way I can get the programme to automatically drop variables
without me having to explicitly tell it to do so? As you can see
below, the names y`x'iqq y`xless1'iqq are set to change as x and
xless1 changes.
if `j'~=`depmax' { ;
tempvar y`x'iqq y`xless1'iqq;
capture drop `y`x'iqq' ;
if _rc == 0 { local dropvar="`dropvar' `y`x'iqq`" } ;
ge `y`x'iqq' = 0 `if' ;
replace `y`x'iqq'=( `phiwj' ) / ( `PHIwj' - `PHIwj_1' ) if `1'==`j'
& `ifexp' ;
} ;
