I coded a function with 1 parameter [function fred(p1)] and called it successfully with fres(6). v5 mentallity.
However, decided to experiment with more than 1 parmeter:
function fres(p1,p2). This passed the syntax check.
When I called it with fred(6,8) it said bad or missing parameter!
I used the v6 walk_thru for the build.
Have I hit a non compatible error or what have I done wrong please?

Look for an OLD function thats calling on "fred" with only one parameter.
Now that it is defined as having two parameters, it can ONLY be called
using BOTH parameters.

Otherwise post your whole code and I'll have a look.

Thanks Evilsob.
Parameter numbers were universal.
Just got a function call with 4 parameters working, so I made a mistake (probably very very silly when I find it) elsewhere!
Thanks again for the offer of help.

Well. I promised silly and....
I called it 'fred' so it wouldn't get confused with a dummy function. However it was said dummy function it required (beaten by my own safeguard).
So the single pass compiler beat me again!
Sorry for the inconvenience.
I'm going off to SULK.
Thanks again Evilsob..

No worries. Happens to the best of us....even me!
