:DEFine <step#>,
LOOP,<count>
Programs the LOOP sequence command into the
selected sequence at <step#>. The LOOP sequence
command, together with its associated <count> value
and the NEXT sequence command, provides a means of
repeating a set of sequence steps for a defined number
of times. All sequence steps that exist between the
LOOP sequence command and the NEXT sequence
command shall be executed for <count> number of
times. It is recommended that the LOOP command and
its corresponding NEXT command be in the same
named sequence; nevertheless, they may be in different
named sequences. The ability to place these two
commands in different named sequences allows for the
chaining of a number of named sequences together
using the GOTO command, and then to put a loop
around that entire chain to be repeated a number of
times. The LOOP NEXT command pair does support
nesting to 10 deep, and the count value must be
between 0 and 65535.
Programs the NEXT sequence command into the
selected sequence at <step#>. The NEXT command
must follow a matching LOOP command. The NEXT
command causes sequence execution to resume at the
matching LOOP command, with a count decreased by 1.
Programs the STOP sequence command into the
selected sequence at <step#>. This sequence
command causes sequence execution to stop while the
unit remains at the state of the last command within the
sequence. This command is valid for steps 1 thru 21.
When the PROG:MALLOCATE DEFAULT command is
used, a STOP command is automatically loaded into
step 21 of that new sequence. This STOP may be
overwritten to become a RETURN or GOTO command.
:DEFine
<step#>,GOTO,”name”
Programs the GOTO sequence command into the
selected sequence at <step#>. During sequence
execution, the effect of this sequence command is to
cause execution to transfer to the beginning of the
sequence named “name”. This step is valid for steps 1
thru 21. The name must be in double quotes. See the
PROG:NAME “name” command for how sequences may
be given user defined names.
Programs the PAUSE sequence command into the
selected sequence at <step#>. During sequence
execution the effect of this command is to cause
execution to suspend until a RESUME command is
issued to resume execution. This step is valid for steps
1 thru 20.
Queries the selected sequence for the program
contents at step <step#>. The response will read back
the step type and defined parameters when
programmed. The resolution is defined by the step
type.
