As far as i know you cannot assign variables in such fashion.

Correct syntax would be :
Code:
awk 'BEGIN {a=100} $1>100 { print $1 } $1<=100 { print $1 " lower then 100" }'

or using conditional operator ..
Code:
awk ' {a=100; print ( $1 > a ) ? $1 : $1" lower then 100" }' input

Perhaps you require a function ?
Code:
function testme (field,num)
{
	print ( field > num ) ? field : field " is less then " num
}
{
testme ($1,100)
}
