13 SC Closing parenthesis w/o opening. You programmed a closing parenthesis command
without the associated opening parenthesis command.
14 SC Label incorrectly programmed. A label was set within a parenthetical calculation. This
is illegal because closing parenthesis commands cannot be executed without the
associated opening parenthesis commands.
15 SC Label within a sequence of gating operations. A label was programmed in a
connective operation that was already started. This is illegal because the first
command behind the label would then have to be interpreted, depending on the
program, once as a logical connection and once as a load command.
16 SC Jump within parentheses. A jump statement was programmed within parentheses.
This is not possible because, due to the internal implementation, opening
parentheses must be closed again. This could not happen in the event of a jump.
17 SC Parentheses opened at block end. An EM instruction was programmed after an
opening parenthesis. The parenthesis must be closed again.
18 SC Label defined twice. A label name that was imported with EXTERN from another
module was used again with a LBL or KFIELD instruction. A name reserved for
internal modules (9000–9255) was used with an LBL, KFIELD or EXTERN instruction.
19 SC Word assignment missing. A word logic operation was conducted. However, the
result was not assigned to an operand, but to a new logic operation.
20 SC Logic assignment missing. A logic operation was conducted. However, the result
was not assigned to an operand, but to a new logic operation.
21 SC Word accumulator not loaded. A command was programmed that logically connects,
assigns or manipulates the loaded word accumulator, although the word accumulator
was not previously loaded.
22 SC Logic accumulator not loaded. A command was programmed that logically connects,
assigns or manipulates the loaded logic accumulator, although the logic accumulator
was not previously loaded.
23 SC Accumulators not loaded for opening parenthesis. You programmed an opening
parenthesis command without first beginning a logic or a word sequence.
24 SC Incorrect type in parentheses. Depending on the logic operation formed before a
parenthesis and the parenthesis command used, it is expected that the sequence in
parentheses supplies a result of the same type (word/logic). If the types differ, the
logic operation requested in the open-parenthesis command cannot be formed.
