Dear colleagues,
strings starting with an apostrophe (') sometimes cause weired errors
even if embraced in compound double quotes. For example
. di 1 + match("",`"'whatever"')
produces an error, while
. di match("",`"'whatever"') + 1
or
. di 1 + match("","'whatever")
does not. Even odder:
. lab def x 1 `"'whatever"' /*
*/ 2 whatever
produces an error, while
. lab def x 1 `"'whatever"' 2 whatever
works fine. Similarly ("s" being a string variable):
. gen x = `"'whatever"'==s
is ok, but not
. gen x= s==`"'whatever"'
This is very anoying because it makes it hard to write programs that
work correctly.
Does anyone know a "really" save way to treat strings?
Thanks, ben
