Hi All and a Happy and Properous 2012 to us all!

I want to enhance the Title section of my charts by inserting the day of the week in front of the date: Friday, 12/30/2011.

The DayOfWeek() returns a number. So I need to convert the number to text that says what day it is.

Here is the code I have so far:

for( n = 0; n < 10; n++ )
{
printf("Current n = %f\n", n );

varDayOfWeek = DayOfWeek();

switch(varDayOfWeek)
{
case 0:
varDayOnChart == "Sunday";
printf("Day of week is ") + varDayOnChart + "\n";
break;
case 1:
varDayOnChart == "Monday";
printf("Day of week is ") + varDayOnChart + "\n";
break;
case 2:
varDayOnChart == "Tuesday";
printf("Day of week is ") + varDayOnChart + "\n";
break;
case 3:
varDayOnChart == "Wednesday";
printf("Day of week is ") + varDayOnChart + "\n";
break;
case 4:
varDayOnChart == "Thursday";
printf("Day of week is ") + varDayOnChart + "\n";
break;
}

The error occurs on the last line. The "}" is highlighted and the error message is : Syntax error, unexpected send. Is there semicolon missing at end of the previous line?"

Anyone who can help shed some light on fixing this?

I typically use with { }

So:

switch (varDayOfWeek)
{

case 0:
{
varDayOnChart == "Sunday";
printf("Day of week is ") + varDayOnChart + "\n";
break;
}

}

But don't have AmiBroker or a C++ compiler, so can't say for sure if that is the syntax problem.

It has been a while since I used C++, but you should check strftime and you can format the time and just use a single deceleration with no switch statement.

Also, I don't see a close bracket for the open bracket below the for statement, unless you just aren't showing it.

@OP,

you don't need switch

Instead use this function and put it to the Include folder of Amibroker e.g. as DayOfWeekName.afl or whatever name

Code

function DayOfWeekName()
{
	dow = DayOfWeek();
	dayStr = 
		WriteIf(dow == 0, "Sunday", 
		WriteIf(dow == 1, "Monday",
		WriteIf(dow == 2, "Tuesday",
		WriteIf(dow == 3, "Wednesday",
		WriteIf(dow == 4, "Thursday",
		WriteIf(dow == 5, "Friday",
		WriteIf(dow == 6, "Saturday", "Unknown")))))));

	return dayStr;
}

then in your main code call that function

Code

#include <DayOfWeekName.afl>;

dow = DayOfWeekName();

.
.
.
.

then the title of that main code could look as follows

Code

_N(Title = StrFormat("{{NAME}} - {{INTERVAL}} - " + dow + " {{DATE}} Open %g, Hi %g, Lo %g, Close %g (%.1f%%) {{VALUES}}", O, H, L, C, SelectedValue( ROC( C, 1 ) ) ));

OR

you could use something completely different (so forget about the above one)

like this

Code

DayName = StrExtract("Sunday,Monday,Tuesday,Wednesday,Thursday,Friday,Saturday", SelectedValue(DayOfWeek()));

_N(Title = StrFormat("{{NAME}} - {{INTERVAL}} - " + DayName + " {{DATE}} Open %g, Hi %g, Lo %g, Close %g (%.1f%%) {{VALUES}}", O, H, L, C, SelectedValue( ROC( C, 1 ) ) ));
