RE: st: local variables and running do files

[Nick Cox <n.j.cox@durham.ac.uk>]

You must change 

sum `var' 

to 

sum $var 

as Jorge did explain. 

It's a matter of taste, but I wouldn't use global macros here; I would pass arguments to do-files as in my previous.

I tried global macros but it does not work either...
Thanks,


. do "/var/folders/Xn/Xnl4Mq-lGR4-mNII1zm-Wk+++TI/-Tmp-//SD17268.000000"

. global var "var1 var2"

.
end of do-file

. do "/var/folders/Xn/Xnl4Mq-lGR4-mNII1zm-Wk+++TI/-Tmp-//SD17268.000000"

. sum `var'

.
end of do-file
