Trying to use foreach and if to define a local

[Steen Harsted]

Hi Stata users

I now have three days of experience with Stata and I really like the program so far. I have now run into a problem that I can't figure out how to solve, and I'm hoping one of you can help me.

I am trying to combine "foreach" and "if" to define a local value using the below code.
I get the error: "num not found"

I cant figure if I´m wrong on "foreach" or "if" or both.

Can you see what I am doing wrong? Or help me find an alternative solution?

Thank you for reading this.

foreach num of numlist 1/5 {
if num == 1 local Jname Squat
if num == 2 local Jname Squat_Jumps
if num == 3 local Jname Drop
if num == 4 local Jname Drop_Vertical_Jump
if num == 5 local Jname Static_Broad_Jump
use "`Jname'.dta"
.......
}

 if num == 1 local Jname Squat

should be

 
 if `num' == 1 local Jname Squat

and so forth.

There are several ways to do that more quickly, including

 
 foreach f in Squat Squat_Jumps Drop Drop_Vertical_Jump Static_Broad_Jump {      use `f' }

The code at the end of post #2 cannot be executed as shown.

. foreach f in Squat Squat_Jumps Drop Drop_Vertical_Jump Static_Broad_Jump {      use `f' }
program error:  code follows on the same line as open brace
r(198);

It should be

foreach f in Squat Squat_Jumps Drop Drop_Vertical_Jump Static_Broad_Jump {
  use `f'
}

Friedrich: Correct. I should have spotted that.

Thank you very much both of you. The codes work like a charm
