ksh problem

when declaring a variable e.g.
export DAYS

what checking / how can i check that the value assigned only contains numeric characters or integers ?

Use:

typeset -i VARIABLE=value

That will guarantee that it is an integer. Trying to assign a string to the variable will result in the value being set to zero.
