One important note: varname is not case sensitive.
Both
for( i = 10; i <=40; i=i+10 )
{
VarSet( "MA"+i, MA( C, i ) );
Plot(VarGet("MA"+i),"MA"+i,i/5,1);
}
and
for( i = 10; i <=40; i=i+10 )
{
VarSet( "MA"+i, MA( C, i ) );
Plot(VarGet("ma"+i),"ma"+i,i/5,1);
}
will equally define and plot the ma10, ma20, ma30 and ma40.
[The user is excused to forget the CapsLock from time to time...]
This was already available, amibroker had no problem to recognize in
MA20=MA(C,20);
Plot(ma20,"",1,1);
that ma20 was MA20 and this friendly property is preserved in the new
functions.
