Program is too long (RAM overflow) (insufficient
memory for the program code to be generated.)
Assign with parenthesis (an =, S, SN, R, RN or PS
instruction has been programmed, although arithmetic
parenthesis are open)
Excessive nesting of parentheses (more than 16
parentheses are open)
Jump within a gating sequence (unconditional jump
has been programmed, although the gating sequence

Logic Assign missing (a Word instruction has been

accumulator does not contain a definite value)
