Value

"\\(\\$MAIN\\$\\|\\<[a-zA-Z][a-zA-Z0-9_$:]*\\([      ]*\n[   ]*[a-zA-Z0-9_$:]+\\)*\\)[       \n]+\\([0-9]+\\([       ]*\n[   ]*[0-9]+\\)*\\)[        \n]+\\([^       \n]+\\([        ]*\n[   ]*[^    \n]+\\)*\\)"

Documentation

A regular expression to parse out the file name and line number.

The 1st group should match the subroutine name. The 3rd group is the line number. The 5th group is the file name. All parts may contain linebreaks surrounded by spaces. This is important in IDL5 which inserts random linebreaks in long module and file names.
