Alright i'm having problems with this loop. Basically once the script is ran a parameter is required. Once entering the parameter it displays that in LIMIT. Alright so now the problem, I need my loop to ask my user for a number, and if that number is less than the limit then sum the input values until it reaches the limit.
example output of what i need
LIMIT = 50
please enter a number: 10
I = 10 SUM = 10
please enter a number: 15
I = 15 SUM = 25
please enter a number: 20
I = 20 SUM = 40
please enter a number: 15
done!
this is the code i have so far, the SUM PART is messed up and i dont know how to exit the loop and display done once it reached the limit.

Hello all
I am having problems using a bash script to read the input from the user and checking that its a valid number. I only want the user to input a maximum of a 3 number string (321 , 521 , 871 etc.). Anything longer or that includes a chararcter or symbol will display an error message.

ilaenv
ILAENV(l) ) ILAENV(l)
NAME
ILAENV - i called from the LAPACK routines to choose problem-dependent parameters for the local environment
SYNOPSIS
INTEGER FUNCTION ILAENV( ISPEC, NAME, OPTS, N1, N2, N3, N4 )
CHARACTER*( * ) NAME, OPTS
INTEGER ISPEC, N1, N2, N3, N4
PURPOSE
ILAENV is called from the LAPACK routines to choose problem-dependent parameters for the local environment. See ISPEC for a description of
the parameters.
This version provides a set of parameters which should give good, but not optimal, performance on many of the currently available comput-
ers. Users are encouraged to modify this subroutine to set the tuning parameters for their particular machine using the option and problem
size information in the arguments.
This routine will not function correctly if it is converted to all lower case. Converting it to all upper case is allowed.
ARGUMENTS
ISPEC (input) INTEGER
Specifies the parameter to be returned as the value of ILAENV. = 1: the optimal blocksize; if this value is 1, an unblocked algo-
rithm will give the best performance. = 2: the minimum block size for which the block routine should be used; if the usable block
size is less than this value, an unblocked routine should be used. = 3: the crossover point (in a block routine, for N less than
this value, an unblocked routine should be used) = 4: the number of shifts, used in the nonsymmetric eigenvalue routines = 5: the
minimum column dimension for blocking to be used; rectangular blocks must have dimension at least k by m, where k is given by
ILAENV(2,...) and m by ILAENV(5,...) = 6: the crossover point for the SVD (when reducing an m by n matrix to bidiagonal form, if
max(m,n)/min(m,n) exceeds this value, a QR factorization is used first to reduce the matrix to a triangular form.) = 7: the number
of processors
= 8: the crossover point for the multishift QR and QZ methods for nonsymmetric eigenvalue problems. = 9: maximum size of the sub-
problems at the bottom of the computation tree in the divide-and-conquer algorithm (used by xGELSD and xGESDD) =10: ieee NaN arith-
metic can be trusted not to trap
=11: infinity arithmetic can be trusted not to trap
NAME (input) CHARACTER*(*)
The name of the calling subroutine, in either upper case or lower case.
OPTS (input) CHARACTER*(*)
The character options to the subroutine NAME, concatenated into a single character string. For example, UPLO = 'U', TRANS = 'T',
and DIAG = 'N' for a triangular routine would be specified as OPTS = 'UTN'.
N1 (input) INTEGER
N2 (input) INTEGER N3 (input) INTEGER N4 (input) INTEGER Problem dimensions for the subroutine NAME; these may not
all be required.
>= 0: the value of the parameter specified by ISPEC < 0: if ILAENV = -k, the k-th argument had an illegal value.
FURTHER DETAILS
The following conventions have been used when calling ILAENV from the LAPACK routines:
1) OPTS is a concatenation of all of the character options to
subroutine NAME, in the same order that they appear in the
argument list for NAME, even if they are not used in determining
the value of the parameter specified by ISPEC.
2) The problem dimensions N1, N2, N3, N4 are specified in the order
that they appear in the argument list for NAME. N1 is used
first, N2 second, and so on, and unused problem dimensions are
passed a value of -1.
3) The parameter value returned by ILAENV is checked for validity in
the calling subroutine. For example, ILAENV is used to retrieve
the optimal blocksize for STRTRI as follows:
NB = ILAENV( 1, 'STRTRI', UPLO // DIAG, N, -1, -1, -1 )
IF( NB.LE.1 ) NB = MAX( 1, N )
