Hi,
  Can I type cast a variable used in scripts, if so how.
  Thanks in advance.
caroline.c

Shell scripts have no types so you have nothing to cast i.e. you can
handle the same variable both as a number or as a string.

print "Navigare necesse est, vivere non est necesse - Pompeius\n";

You can do a 'little' type casting, although I suspect it may not be
what you have in mind.
Check out man ksh and look for typeset.

Not true for ksh:

     $ typeset -i10 x=0
     $ unset y
     $ y=0
     $ x=x+1
     $ y=y+1
     $ print "x=$x y=$y"
     x=1 y=y+1

In bash, you can declare a variable as an integer bashing :
declare -i myvariable
This will force arithmetic evaluation whe the variable is assigned (like 'let' or $(( ..)) expressions)
