NAME

SYNOPSIS

9       readfile filename
10
11
12       longline [filename]

DESCRIPTION

16       The readfile function reads filename and copies it to stdout. No trans‐
17       lation of NEWLINE is done. It keeps track of the longest line it  reads
18       and if there is a subsequent call to longline, the length of that line,
19       including the NEWLINE character,  is returned.
20
21
22       The longline function returns the length, including the NEWLINE charac‐
23       ter,  of the longest line in filename. If filename is not specified, it
24       uses the file named in the last call to readfile.

EXAMPLES

27       Example 1 Typical use of readfile and longline
28
29
30       Here is a typical use of readfile and longline in a text frame  defini‐
31       tion file:
32
33
34            .
35            .
36            .
37         text="`readfile myfile`"
38         columns=`longline`
39            .
40            .
41            .

DIAGNOSTICS

61       If  filename  does not exist, readfile will return  FALSE (that is, the
62       expression will have an error return).
63
64
65       longline returns  0 if a readfile has not previously been issued.
66

NOTES

68       More than one descriptor can call readfile in the same frame definition
69       file.  In  text  frames,  if  one  of those calls is made from the text
70       descriptor, then a subsequent use of longline will always get the long‐
71       est  line  of  the  file  read by the readfile associated with the text
72       descriptor, even if it was not the most recent use of readfile.
