Program Logic Control
N{constant} – Line label
O{constant} – Line label, alternate entry form
GOTO{data} – Jump to specified line label; no return
GOSUB{data}[{letter}{axis}...] – Jump to specified line label [with arguments] and return
CALL{data}[.{data}][{letter}{axis}...] – Jump to specified program [and label] [with
arguments] and return.
RETURN –- Return program operation to most recent GOSUB or CALL
READ ({letter} [,{letter}...]) – Read argument into subroutine/subprogram from calling
line
G{data} – Gnn[.mmm] interpreted as CALL 1000.nnmmm (PROG 1000 provides subroutines for
desired G-Code actions)
M{data} – Mnn[.mmm] interpreted as CALL 1001.nnmmm (PROG 1001 provides subroutines for
desired M-Code actions)
T{data} – Tnn[.mmm] interpreted as CALL 1002.nnmmm (PROG 1002 provides subroutines for
desired T-Code actions.)
D{data} – Dnn[.mmm] interpreted as CALL 1003.nnmmm (PROG 1003 provides subroutines for
desired D-Code actions.)
S{data} – Set Q127 to value of {data} (spindle command)
PRELUDE1{call command} – Enable modal execution of call command before subsequent moves
PRELUDE0 – Disable modal PRELUDE calls
IF ({condition}){action} – Conditionally execute single-line action
IF ({condition}) – Conditionally execute following statements
ELSE {action} – Execute single-line action on previous false condition
ELSE –- Execute following statements on previous false IF condition
ENDIF – Mark end of conditionally executed branch statements
WHILE ({condition}){action} – Do single-line action as long as condition true
WHILE ({condition}) – Execute following statements as long as condition true
ENDWHILE – Mark end of conditionally executed loop statements
BLOCKSTART – So all commands until BLOCKSTOP to execute on Step
BLOCKSTOP – End of “single-step” statements starting on BLOCKSTART
STOP – Halt program execution, ready to resume
WAIT – Use with WHILE to halt execution while condition true
LOCK{constant},P{constant} – Check/set process-locking bit
UNLOCK{constant} – Clear process-locking bit
