Shell Programming and Scripting

Hi
I work in ksh88 and have a file which has several "set -A " statements:

set -A PNUM_LSTM 2713 4124 2635 270 2529 2259 2214
set -A PNUM_LSTM $*
for pn in ${PNUM_LSTM[*]}
etc...

I need to add another number, lets say 555, to the first line ONLY so only the
the first line will be updated and will look like this:

set -A PNUM_LSTM 555 2713 4124 2635 270 2529 2259 2214

Thanks a lot for any advice.... -A

i'm not aware of push/pop array in unix. i think you need to re-set your array everytime you add an element.

is there a way to do it using "awk" or "sed" ?
