see <<help extended_fcn>> for the syntax of extended macros.
For example (and using a common construct to dispense with explictly naming the
macro):
. sysuse auto
. foreach var of varlist _all {
2. display " `var' " _col(20) "`: type `var''"
3. }
make str18
price int
mpg int
rep78 int
headroom float
trunk int
weight int
length int
turn int
displacement int
gear_ratio float
foreign byte
In case your font makes all those quotes hard to decipher:
"`: type `var''"
is
dq lsq : type lsq var rsq rsq dq
Perhaps closer to the program fragment you will need:
. foreach var of varlist price headroom displacement gear_ratio foreign {
2. if "`:type `var''" == "float" {
3. di "`var' is floating point"
4. }
5. }
headroom is floating point
gear_ratio is floating point
