Back in the days of programs on punched cards, FORTRAN used columns 1-6 for statement numbers, column 7 being anything other than a space indicated it was a continuation of the previous card, columns 8-72 were program text, and columns 73-80 were ignored by the compiler (sometimes containing sequence numbers that could be used to sort the deck back into order using a card sorter in case you dropped your program deck). You'll have to read the man page for your compiler; there is probably an option to specify which columns in your input file contain program text.

PS Note that yellow text on a gray CODE tag background is almost unreadable.

COLUMN(1)						    BSD General Commands Manual 						 COLUMN(1)

NAME
column -- columnate lists SYNOPSIS
column [-tx] [-c columns] [-s sep] [file ...] DESCRIPTION
The column utility formats its input into multiple columns. Rows are filled before columns. Input is taken from file operands, or, by default, from the standard input. Empty lines are ignored. The options are as follows: -c Output is formatted for a display columns wide. -s Specify a set of characters to be used to delimit columns for the -t option. -t Determine the number of columns the input contains and create a table. Columns are delimited with whitespace, by default, or with the characters supplied using the -s option. Useful for pretty-printing displays. -x Fill columns before filling rows. Column exits 0 on success, >0 if an error occurred. ENVIRONMENT
COLUMNS The environment variable COLUMNS is used to determine the size of the screen if no other information is available. EXAMPLES
(printf "PERM LINKS OWNER GROUP SIZE MONTH DAY HH:MM/YEAR NAME " ; ls -l | sed 1d) | column -t SEE ALSO
colrm(1), ls(1), paste(1), sort(1) HISTORY
The column command appeared in 4.3BSD-Reno. AVAILABILITY
The column command is part of the util-linux-ng package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux-ng/. BSD
