Is it possible to return a string from a function?

If I try something like this:

Function test(Inp$)
	Local output$="test"
	Print Inp$
	Return output$
End Function

I get is an 'Unable to convert from 'String' to 'Int' compile error.

Yeah you need to specify the return type of the function:

Function test$(Inp$)

or

Function test:String(Inp$)

either works, I use the sorter one.

Do you code with Strict at the top? I advise this.

Thanks, I just figured it out myself as well, and then I saw your response.

Not always... Sometimes I start without, and put it there later, fixing potential problems problems.

I would recommend to use it always - I'm going even further and use superstict.
Keeps the Code clean from all kind of misspellings and the like. And you get used to it very fast.

Yes, always use strict. Not to fix problems, but because BlitzMax behaves elementally different when it comes to local - global - variable scopes if not strict is used. (it works then the Blitz3D way which means: a function is a scope and the whole program is a scope. But it does not know of loop, branch or any other local scopes!)

using strict has saved me hours that I used to waste in BPlus when I accidentalyy misspelled a variable name and couldn't figure out why my code was going nuts until I realised the misspelling cos I was allow to use a misspelled var, it was just initialised at 0 and used!

* uses superstrict always..

Tho, strict naming conventions does add some value in the coding process. The more uniform and regular your var/method-names are, the better.
