Print and File#

Print is used to output information to the screen or a file. The most important application is debugging, to verify that the program’s execution flow and computational logic are correct.

Syntax#

1
Print([OutputTarget], Expression1, Expression2, ...);

Syntax Element	Optional	Description
`OutputTarget`	Optional	Specifies the output target. Defaults to `PowerLanguage Editor Output Log`
`Expression`	Required	String, TrueFalse, or Numerical

Output Target (OutputTarget)#

Output Target	Description
(Not specified)	Output to `PowerLanguage Editor Output Log` (default)
`Printer`	Specifies the default printer as the output target
`File("FilePath")`	Specifies the file at `FilePath` as the output target. If the file does not exist, a new file will be created

Numeric Output Format#

If Expression is numerical, you can use the Expression:C:D syntax to specify the output format:

Syntax Element	Description
`C`	The minimum number of output characters (integer + decimal point + decimal places). If the number of characters is less than `C`, leading spaces will be added in front of the value to fill up
`D`	The number of decimal places. If the number of decimal places is greater than `D`, the value will be rounded to `D` places

The default output format is a minimum of 7 characters and 2 decimal places.

Example#

Print 0.10 in the PowerLanguage Editor Output Log (3 leading spaces are added in front of 0.10).

1
Print(.1);

Print 1.556 in the PowerLanguage Editor Output Log (1 leading space is added in front of 1.556).

1
Print(1.555555:6:3);

Output CurrentDate and CurrentTime to the file C:\test.txt.

1
Print(File("C:\test.txt"), CurrentDate, CurrentTime);
