!<ERROR PROGRAM: INVALID IMMEDIATE VALUES>

!Purposes: 
!This programs tests if the assembler can detect and report 
!invalid immediate values 

!Description: 
!A representative operation is choosen for each instruction type 
!and the following range of immediate values are tested: 
!(1) the minimum possible value that should be accepted
!(2) zero (if it is not already the minimum possible value) 
!(3) a middle range negative value (if allowed)
!(4) a middle range positive value
!(5) the maximum possible value that should be accepted
!(6) a negative value that exceeds the minimum possible value
!    (should generate a warning message and require truncation)
!(7) a positive value that exceeds the maximum possible value
!    (should generate a warning message and require truncation)
