listOfParams wasn't an array either; your arguments weren't ever three things.
I never said the input starts out as an array or an array of 3 things. I said it is a list which I could place into a variable. And the list contains quoted strings containing white space.
I have no control over the generation of the input - but of course I can massage it within scriptA before sending it on to scriptB. I merely tried to emulate the input with an echo of that variable. Your IFS block of code is useful. It demonstrated that my "emulated" input was incorrect in regards to what I was receiving during my earlier observations.
With your IFS block I saw the following printout:
Obviously by placing that input into an array - it will contain four elements. (I tried it anyways.) But to get the desired interpretation of this list as 3 elements, I still believe "eval" is necessary.
So thank you for your input. It was very helpful.

cgtts2
CGTTS2(l) ) CGTTS2(l)
NAME
CGTTS2 - solve one of the systems of equations A * X = B, A**T * X = B, or A**H * X = B,
SYNOPSIS
SUBROUTINE CGTTS2( ITRANS, N, NRHS, DL, D, DU, DU2, IPIV, B, LDB )
INTEGER ITRANS, LDB, N, NRHS
INTEGER IPIV( * )
COMPLEX B( LDB, * ), D( * ), DL( * ), DU( * ), DU2( * )
PURPOSE
CGTTS2 solves one of the systems of equations A * X = B, A**T * X = B, or A**H * X = B, with a tridiagonal matrix A using the LU factoriza-
tion computed by CGTTRF.
ARGUMENTS
ITRANS (input) INTEGER
Specifies the form of the system of equations. = 0: A * X = B (No transpose)
= 1: A**T * X = B (Transpose)
= 2: A**H * X = B (Conjugate transpose)
N (input) INTEGER
The order of the matrix A.
NRHS (input) INTEGER
The number of right hand sides, i.e., the number of columns of the matrix B. NRHS >= 0.
DL (input) COMPLEX array, dimension (N-1)
The (n-1) multipliers that define the matrix L from the LU factorization of A.
D (input) COMPLEX array, dimension (N)
The n diagonal elements of the upper triangular matrix U from the LU factorization of A.
DU (input) COMPLEX array, dimension (N-1)
The (n-1) elements of the first super-diagonal of U.
DU2 (input) COMPLEX array, dimension (N-2)
The (n-2) elements of the second super-diagonal of U.
IPIV (input) INTEGER array, dimension (N)
The pivot indices; for 1 <= i <= n, row i of the matrix was interchanged with row IPIV(i). IPIV(i) will always be either i or i+1;
IPIV(i) = i indicates a row interchange was not required.
B (input/output) COMPLEX array, dimension (LDB,NRHS)
On entry, the matrix of right hand side vectors B. On exit, B is overwritten by the solution vectors X.
LDB (input) INTEGER
The leading dimension of the array B. LDB >= max(1,N).
