In Stata, I try to save a dta file using local and global macros together in file names.

However, the local macros are not parsed correctly.

The global macro result is a folder directory which is: 

global result "C:\Users\...\....\..."

The local macro x is defined in a loop:

foreach x of varlist ret_yyy { 
    .......
    save "$result\Reg_Coefficients\`x'", replace
}

This only produces a file under a "result" folder with name "Reg_Coefficients`x'".

What I expect is to save a file under folder "Reg_Coefficients".

  • I find that when I add something before local "`x'" and after "Reg_Coefficients\", it works correctly. save "$result\Reg_Coefficients\reg_`x'" , replace – Gen May 31 '19 at 16:21
  • Yes, forward slashes are easier to use but placing "\\" before a local macro will also work. –  May 31 '19 at 18:51

Use forward slashes (/) instead:

sysuse auto, clear
global result "C:/Users/.../..../..."

foreach x of varlist * { 
    display "$result/Reg_Coefficients/`x'"
}

    -search backslash- for why. The backslash is an escape character as well as a separator in Windows filepaths. – Nick Cox May 31 '19 at 17:59
