Attempt to redefine a HSC by executing another HDEF
instruction for the same HSC
Simultaneous execution of XMT/RCV instructions on Port 1
Illegal numeric value in compare contact instruction
Program too large to compile; reduce program size
Illegal instruction; check instruction mnemonics.
Missing MEND or instruction not allowed in main program: add
MEND instruction, or remove
Missing FOR; add FOR instruction or delete NEXT instruction.
Missing NEXT; add NEXT instruction or delete FOR instruction.
Missing label (LBL, INT, SBR); add the appropriate label.
Missing RET or instruction not allowed in a subroutine: add RET
to the end of the subroutine or remove incorrect instruction
Missing RETI or instruction not allowed in an interrupt routine:
add RETI to the end of the interrupt routine or remove incorrect
instruction.
Illegal JMP to or from an SCR segment
Duplicate label (LBL, INT, SBR); rename one of the labels.
Illegal label (LBL, INT, SBR); ensure the number of labels
allowed was not exceeded.
Illegal parameter; verify the allowed parameters for the
instruction.
Range error (with address information); check the operand
ranges.
Error in the count field of an instruction (with count information);
verify the maximum count
