#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()
