Well you can type:
VAR=x export VAR
which is technically one command. (Note there is no semi-colon between the
VAR=x and export VAR).
In bash and ksh you can type
export VAR=x
In standard bourne shell you can write a function:
If you like csh behaviour then enter this function:
setenv()
{
eval "$1=$2"
export "$1"
}
setenv MYVAR xxx
env | grep MYVAR
MYVAR=xxx
