Dim Variations

[Charles Pegge]

Dim uses smart syntax to accept variables and initialisers in a variiety of formats - to suit all tastes :)

Charles,

your O2H is very impressive, I know it will deliver good amount of horsepower for time critical applications ;)
I just tried more "ThinBasicish" version of your


dim as long i,j,k, as string s,t


that means


dim i,j,k as long, s,t as string

thinking it might confuse O2H ... no it didn't, worked perfectly :occasion:

Well Petr I always felt that dim statements are quite restrictive, and there's no perfect agreement between different dialects of BASIC. If the type has not been determined at the begining of the list then it collects all the names and their assignment expressions and looks ahead. The second important rule is that if a comma appears at the end of a line (ignoring comments) then the statement continues.
Comments and blank lines are skipped, which gives you greater flexibility than using traditional underscores.
