This thread is about the PRINT keyword in EasyLanguage


Print

Sends one or more specified expressions to the PowerLanguage Editor Output Log or another output target, if specified.
Any combination of string, true/false, numerical series, or numerical expressions can be specified.


Usage

Print([OutputTarget],Expression1,Expression2, etc.)

Parameter inside the square brackets is optional



Parameters

OutputTarget - an optional parameter; specifies an output target other then the PowerLanguage Editor Output Log; the parameter must be followed by a comma.

There are two optional output targets:

Printer

Specifies the default printer as the output target.

File("PathFilename")

Where: PathFilename - a string expression specifying the path and filename

Specifies an ASCII file as the output target; if the specified file does not exist, the file will be created.

If OutputTarget is not specified, the output will be sent to the PowerLanguage Editor Output Log.



Expression - a string, true/false, numerical series, or numerical expression; any number of valid expressions, separated by commas, can be used

A string expression must be enclosed in quotation marks:

"String Expression"


A numerical expression can be formatted to specify the minimum number of characters, including the decimal point, and the number of decimal places, to be used for the output:

Expression:C: D

Where:
C - minimum number of characters
D - number of decimal places

The default output format for a numerical expression is two decimal places and a minimum of seven characters.

If the number of decimal places in the numerical expression is more than the specified number, the value will be will be rounded off to the specified number of decimal places.

If the number of characters in the output is less than the specified minimum, leading spaces will be added to bring the output to the specified minimum value.



Examples

Print(.1);
will print 0.10 in the PowerLanguage Editor Output Log, with three leading spaces inserted

Print(1.555555:6:3);
will print 1.556 in the PowerLanguage Editor Output Log, with one leading space inserted

Print(Printer,"Print Test");
will send the string expression "Print Test" to the default printer

Print(File("C: \test.txt"),CurrentDate,CurrentTime );
will save the output of CurrentDate and CurrentTime to the test.txt file in the root directory of the C: hard drive

It is probably worth mentioning that Print can be very useful for debugging something that runs but does not run correctly or to check that things are consistent.

You can use print statements to output variables or to help monitor the path of the program through loops and conditional statements.

[aaa]

inputs:
Length( 14 ) ;

if CurrentBar > Length then
Plot1( CMO( Length ), "CMO" ) ;
Plot2( 0, "Zero" ) ;
print( plot1 ) ;

In the CMI indicators nothing is printed in the output PLE window except 53.49

print( plot1 ) = what is this for ?

For debugging ?

In case of errors it will print them ?

[Tams]

It is supposed to print out the value of "plot1" at the end of each bar.
You can use the output for debugging,
or if it is output to a text file, for record keeping.


variations you can try:

print( text(plot1) ) ;

print( NumToStr(plot1, 6) ) ;

print( BarNumber, plot1 ) ;

print( " Date=", date, " Time=", time, " CMI=", plot1 ) ;

I like this one

print(File("Dtext.asc") ,plot1);

Everything is said, specially for perfect beginners.

I have posted a PRINT example here:

p.s.
it also uses the keyword FILEAPPEND.
