#line

FreeBASIC

#line
 
Preprocessor directive to set the current line number and file name

Syntax

#line number [ "name" ]

Parameters

number
new line number
"name"
new file name (optional)

Description

Informs the compiler of a change in line number and file name and updates the __FILE__ and __LINE__ macro values accordingly.

Both compile time messages and run-time messages are affected by this directive.

This directive allows other programs to generate source code for the FreeBASIC compiler and have it return warning and/or error messages that refer to the original source used by the other program.

Example

#line 155 "outside.src"

Error 1000

'' Output is:
'' Aborting due to runtime error 1000 at line 157 of outside.src()
