RE: st: RE: RE: tabstat: how to save...
The reason I said what I said is when I did:
. do "C:\DOCUME~1\waterb\LOCALS~1\Temp\STD02000000.tmp"
. local incidnsum
. sum incidn, meanonly
. scalar `incidnsum' = r(sum)
= invalid name
end of do-file
. help scalar
revealled some example on how to use scalar, where none was put in Stata quotes ` '. This led me to surmise that it is probably version issue of scalar syntaxes. But on closer look I realised that perhaps you are referring to may lax ( due to ignorance) use of -local- rather -tempname- in my -do- file, and consequently having to use -scalar- without `'. Is this what you meant by your warning? Although I think your warning refers to [P] Macro, I would appreciate if you can direct me to the pertinent reference in the manuals if this is assumption was not correct. Nevertheless, I have used your exact example using -tempname- and -scalar `foosum'-.
