in ksh you can use typeset -L (or -R) to define space padded strings
when you are passing a value with embedded spaces you always need to double quote the variable, otherwise echo (or any other function/utility) would treat multiple consecutive spaces as a single argument separator.

echo "100 100 100 100" > temp.txt

concat
concat(3tcl) Tcl Built-In Commands concat(3tcl)__________________________________________________________________________________________________________________________________________________NAME
concat - Join lists together
SYNOPSIS
concat ?arg arg ...?
_________________________________________________________________DESCRIPTION
This command joins each of its arguments together with spaces after trimming leading and trailing white-space from each of them. If all
the arguments are lists, this has the same effect as concatenating them into a single list. It permits any number of arguments; if no args
are supplied, the result is an empty string.
EXAMPLES
Although concat will concatenate lists, flattening them in the process (so giving the following interactive session):
% concat a b {c d e} {f {g h}}
a b c d e f {g h}
it will also concatenate things that are not lists, as can be seen from this session:
% concat " a b {c " d " e} f"
a b {c d e} f
Note also that the concatenation does not remove spaces from the middle of values, as can be seen here:
% concat "a b c" { d e f }
a b c d e f
(i.e., there are three spaces between each of the a, the b and the c).
