foreach var of varlist _all {
egen z`var' = std(`var')
}
Instead of using the keyword -_all- to represent every variable in the
data set (this may not be appropriate) you could of course specify the
variables individually:
foreach var of varlist var1 var2 var3 var4 <etc> {
egen z`var' = std(`var')
}
or use wildcards if the variable stub is common:
foreach var of varlist var* {
egen z`var' = std(`var')
}
or use lists of variables that are adjacent in the data set:
foreach var of varlist var1-var36 {
egen z`var' = std(`var')
}
see -help foreach- and -help varlist-

Statlisters,
I know this is a really basic question, but I really can't figure something
out:
I want to standardize the variables in my dataset (there are 36) without
typing "egen zvar1=std(var1)" 36 times.
Is there a quicker way to get Stata to standardize all variables in a dataset
at once?
I searched through some past archives before filling your inboxes with what
feels like a way-too-simple question but didn't find anything. Any advice?
Many thanks, and Happy New Year.
