NAME


asa - convert FORTRAN carriage-control output to printable form

SYNOPSIS


asa [-f] [file]...


DESCRIPTION


The asa utility will write its input files to standard output, mapping
carriage-control characters from the text files to line-printer control
sequences.


The first character of every line will be removed from the input, and the
following actions will be performed.


If the character removed is:

SPACE
The rest of the line will be output without change.


0
It is replaced by a newline control sequence followed by the
rest of the input line.


1
It is replaced by a newpage control sequence followed by the
rest of the input line.


+
It is replaced by a control sequence that causes printing to
return to the first column of the previous line, where the rest
of the input line is printed.


For any other character in the first column of an input line, asa skips
the character and prints the rest of the line unchanged.


If asa is called without providing a filename, the standard input is
used.

OPTIONS


The following option is supported:

-f
Start each file on a new page.


OPERANDS


The following operand is supported:

file
A pathname of a text file used for input. If no file operands are
specified, or `-' is specified, then the standard input will be
used.


EXAMPLES


The command

a.out | asa | lp


converts output from a.out to conform with conventional printers and
directs it through a pipe to the printer.


The command

asa output


shows the contents of file output on a terminal as it would appear on a
printer.


The following program is used in the next two examples:

write(*,'(" Blank")')
write(*,'("0Zero ")')
write(*,'("+ Plus ")')
write(*,'("1One ")')
end


Both of the following examples produce two pages of output:


Page 1:

Blank

ZeroPlus


Page 2:

One


Example 1: Using actual files



a.out > MyOutputFile
asa < MyOutputFile | lp


Example 2: Using only pipes



a.out | asa | lp
