It uses space as s separator between words. So when the read statement is executed on that particular line, label will contain xVal , dummy will contain = and val will contain 10 .
So if we use this line instead, then it should work..
You will probably want to use a different name than "dummy" since now it has a function..

Hi all,
I have a variable say var1 (output from somewhere, which I can't change)which store something like this:

Hi,
I need to parse a simple text file like below and store the word that starts with BR* to a variable say $BRno. I need to do this in sh script.

When script is running you only see when some of the commands are not successfull.
Is there a way to see which command are executed and to show the substitution of variables as every line is executed ? (3 Replies)

malloc
MALLOC(3F)MALLOC(3F)NAME
malloc, free, falloc - memory allocator
SYNOPSIS
subroutine malloc (size, addr)
integer size, addr
subroutine free (addr)
integer addr
subroutine falloc (nelem, elsize, clean, basevec, addr, offset)
integer nelem, elsize, clean, addr, offset
DESCRIPTION
Malloc, falloc and free provide a general-purpose memory allocation package. Malloc returns in addr the address of a block of at least
size bytes beginning on an even-byte boundary.
Falloc allocates space for an array of nelem elements of size elsize and returns the address of the block in addr. It zeros the block if
clean is 1. It returns in offset an index such that the storage may be addressed as basevec(offset+1) ... basevec(offset+nelem). Falloc
gets extra bytes so that after address arithmetic, all the objects so addressed are within the block.
The argument to free is the address of a block previously allocated by malloc or falloc; this space is made available for further alloca-
tion, but its contents are left undisturbed. To free blocks allocated by falloc, use addr in calls to free, do not use basevec(offset+1).
Needless to say, grave disorder will result if the space assigned by mallocorfalloc is overrun or if some random number is handed to free.
DIAGNOSTICS
Malloc and falloc set addr to 0 if there is no available memory or if the arena has been detectably corrupted by storing outside the bounds
of a block.
The following example shows how to obtain memory and use it within a subprogram:
integer addr, work(1), offset
...
call falloc ( n, 4, 0, work, addr, offset )
do 10 i = 1, n
work(offset+i) = ...
10 continue
The next example reads in dimension information, allocates space for two arrays and two vectors, and calls subroutine doit to do the compu-
tations:
integer addr, dummy(1), offs
read *, k, l, m
indm1 = 1
indm2 = indm1 + k*l
indm3 = indm2 + l*m
indsym = indm3 + k*m
lsym = n*(n+1)/2
indv = indsym + lsym
indtot = indv + m
call falloc ( indtot, 4, 0, dummy, addr, offs )
call doit( dummy(indm1+offs), dummy(indm2+offs),
. dummy(indm3+offs), dummy(indsym+offs),
. dummy(indv +offs), m, n, lsym )
end
subroutine doit( arr1, arr2, arr3, vsym, vec, m, n, lsym )
real arr1(k,l), arr2(l,m), arr3(k,m), vsym(lsym), v2(m)
...
