Hi,
Is there any way to convert a string into an array in KSH? In other words I want to split the string like this:
STRING="one two three four"
into an array of 4 values splitting on white space. The array should be similar to the one that would be created with the following command:

Hi
Input:
{ committed = 782958592; init = 805306368; max = 1051394048; used = 63456712; }
Result:
A map (maybe Associative Array) where I can iterate through the key/value. Something like this:
for key in $map
do
echo key=$key value=$map
done
Sample output from the map:

ERR(3) Linux Programmer's Manual ERR(3)NAME
err, verr, errx, verrx, warn, vwarn, warnx, vwarnx - formatted error messages
SYNOPSIS
#include <err.h>
void err(int eval, const char *fmt, ...);
void errx(int eval, const char *fmt, ...);
void warn(const char *fmt, ...);
void warnx(const char *fmt, ...);
#include <stdarg.h>
void verr(int eval, const char *fmt, va_list args);
void verrx(int eval, const char *fmt, va_list args);
void vwarn(const char *fmt, va_list args);
void vwarnx(const char *fmt, va_list args);
DESCRIPTION
The err() and warn() family of functions display a formatted error message on the standard error output. In all cases, the last component
of the program name, a colon character, and a space are output. If the fmt argument is not NULL, the printf(3)-like formatted error mes-
sage is output. The output is terminated by a newline character.
The err(), verr(), warn(), and vwarn() functions append an error message obtained from strerror(3) based on the global variable errno, pre-
ceded by another colon and space unless the fmt argument is NULL.
The errx() and warnx() functions do not append an error message.
The err(), verr(), errx(), and verrx() functions do not return, but exit with the value of the argument eval.
CONFORMING TO
These functions are nonstandard BSD extensions.
EXAMPLE
Display the current errno information string and exit:
if ((p = malloc(size)) == NULL)
err(1, NULL);
if ((fd = open(file_name, O_RDONLY, 0)) == -1)
err(1, "%s", file_name);
Display an error message and exit:
if (tm.tm_hour < START_TIME)
errx(1, "too early, wait until %s", start_time_string);
Warn of an error:
if ((fd = open(raw_device, O_RDONLY, 0)) == -1)
warnx("%s: %s: trying the block device",
raw_device, strerror(errno));
if ((fd = open(block_device, O_RDONLY, 0)) == -1)
err(1, "%s", block_device);
