Isn't line_number always equal to or greater than start_line?
It works because the output file is truncated at the right moment.
I would rather go for
Eventually swap the two lines in the loop, to omit the first line (then you do not need to prefix the lable with a nop).
Of course this is a hack. A function puts something on the "return" stack...
I will replace my version with your function and give it a whirl.
I had in fact thought about using #some_label: as both methods would not create an error, something like command not found under normal running but I see your point.
And of course it's a hack, as I always quote "if there is a back door I will find it" and hacks by their nature are back doors....
Hi,
I'm trying to use the goto in ksh but it does not appear to be a valid command. Is that only valid in csh? Anything similar in ksh that I can use?
Appreciate any help you can provide.
Thanks.

Hey Guys.. I just want to know how to use Goto statement in shell scripts.
I know the basic use of statement.
Goto Label
The above statement will search for some label which must be defined in the script itself as:

Hi!
I'm new in these forums and more or less new with Unix. So... here is the question:
does anyone know where is redirected the output of a command when you put >&- after it?
Does it means any standard file descriptor?
Thanks! (2 Replies)
Dear All,
Can any one pls let me the command for how to goback to previous visited directory from the current working directory in SunOS ?
In case of HP-UX; the same can be resolved through "cd -" command.
Thanks in advance!

I have found many source files in the kernel using goto keyword instead of just doing the actual thing. For example:

Is there any specific reason for writing the code like this? The first thought that came to my mind is minimizing... (0 Replies)

struct
STRUCT(1) General Commands Manual STRUCT(1)NAME
struct - structure Fortran programs
SYNOPSIS
struct [ option ] ... file
DESCRIPTION
Struct translates the Fortran program specified by file (standard input default) into a Ratfor program. Wherever possible, Ratfor control
constructs replace the original Fortran. Statement numbers appear only where still necessary. Cosmetic changes are made, including chang-
ing Hollerith strings into quoted strings and relational operators into symbols (.e.g. `.GT.' into `>'). The output is appropriately
indented.
The following options may occur in any order.
-s Input is accepted in standard format, i.e. comments are specified by a c, C, or * in column 1, and continuation lines are specified
by a nonzero, nonblank character in column 6. Normally, a statement whose first nonblank character is not alphanumeric is treated
as a continuation.
-i Do not turn computed goto statements into switches. (Ratfor does not turn switches back into computed goto statements.)
-a Turn sequences of else ifs into a non-Ratfor switch of the form
switch {
case pred1: code
case pred2: code
case pred3: code
default: code
}
The case predicates are tested in order; the code appropriate to only one case is executed. This generalized form of switch state-
ment does not occur in Ratfor.
-b Generate goto's instead of multilevel break statements.
-n Generate goto's instead of multilevel next statements.
-en If n is 0 (default), place code within a loop only if it can lead to an iteration of the loop. If n is nonzero, admit code segments
with fewer than n statements to a loop if otherwise the loop would have exits to several places including the segment, and the seg-
ment can be reached only from the loop.
FILES
/tmp/struct*
/usr/lib/struct/*
SEE ALSO f77(1)BUGS
Struct knows Fortran 66 syntax, but not full Fortran 77 (alternate returns, IF...THEN...ELSE, etc.)
If an input Fortran program contains identifiers which are reserved words in Ratfor, the structured version of the program will not be a
valid Ratfor program.
Extended range DO's generate cryptic errors.
Columns 73-80 are not special even when -s is in effect.
Will not generate Ratfor FOR statements.
