Sounds like you want | (or) instead of & (and)...

gen newvariable = var1 + var2 + var3 if dum1==1|dum2==1|dum3==1

Dear Stata list,

I have a seemingly simple problem that I can't seem to figure out.

1) I would like to generate a new variable :

generate newvariable=var1+var2+var3 if dum1=1 and or dum2=1 and or
dum3=1

In essence I want to sum across var2, var3 and var4 for  a case where
either of the three dummies are equal to 1.

2) If instead I did the following....

generate
newvariable=var1+var2+vhttp://by112fd.bay112.hotmail.msn.com/cgi-bin/com
pose?&curmbox=00000000%2d0000%2d0000%2d0000%2d000000000001&a=8e97f2d6d33
d18578baf68a0a3ed45387544cbaa5b179c9e4483d1f9e6d16955#
Sendar3 if dum1=1 & dum2=1 & dum3=1

.... I would only capture values for var1, var2 and var3 if ALL the
three dummies simultaneously are 1. is this correct? If so I  do not
want this.

Thank you.

Regards,

Gauri
