Turn logical reserved words

Reserved word	Definition
`ALREADY-SUP`	`TRUE` if the Already Supported option is enabled for a Part Handling feature.
`AUTO-ROUND`	`TRUE` if the Auto Round option is enabled in Turn properties.
`BAR-FEED`	`TRUE` if the current operation is a bar feeder operation.
`BAR-PULL`	`TRUE` if the current operation is a bar puller operation.
`COMP-END`	`TRUE` if the move represents the end section for compensation (last element, or move of path), otherwise `FALSE`.
`COMP-MID`	`TRUE` if the move represents the middle section for compensation (between the first and last moves of path), otherwise `FALSE`.
`COMP-ON`	`TRUE` if the Tool nose radius compensation option is enabled in Turn properties.
`COMP-START`	`TRUE` if the move represents the start section for compensation (first element, or move of path), otherwise `FALSE`.
`CSS-ON`	`TRUE` if the Constant surface speed option is selected in Turn properties.
`CUTOFF-CHEK`	`TRUE` if the Cut-off checker option is enabled in the Position the spindle sub-spindle transfer feature (available for Turn and Turn/Mill posts). Checks for lack of torque between spindles to check part has been cut into two pieces, before the sub-spindle is sent home. Avoids damage to jaws and part which would result if Cutoff process was incomplete and the sub-spindle went home.
`CW-SPINDLE`	`TRUE` if the spindle is rotating in the clockwise direction, otherwise `FALSE`.
`DRILLING`	`TRUE` if a drilling-type cycle is used in a segment, otherwise `<DRILLING>` is `FALSE`, and a milling segment is in process.
`EJECT-CHEK`	`TRUE` if the Eject check option is enabled in the Position the spindle page of the Sub-spindle transfer feature (available for Turn and Turn/Mill posts). Causes the machine's 'Eject checker' probe to verify that the previous part has been ejected before grabbing the part from the opposite spindle. Avoids damage if the part has not been ejected.
`FACE-BFACE`	`TRUE` if performing a facing or back-facing operation. This would be true for a Turning feature using a Face or Back face roughing strategy or a Facing feature.
`FINISH`	`TRUE` for a finish operation.
`FLOAT-TAP`	`TRUE` if Tap cycle is set to Floating in FeatureCAM.
`HAS-TOOL`	`TRUE` if the turning operation has a tool associated with it. Used to suppress unnecessary output when an operation does not have a tool (for example bar feed).
`ID`	`TRUE` for Inside Diameter operations.
`IDOD-GROV`	Used to differentiate among G codes that are specialized for grooves on ID (inner diameter), OD (outer diameter), or those on the Face as shown in the examples below: `<IFNOT><IDOD-GROV>` Implies that a Face Groove Cycle program format block is output. `<IF><IDOD-GROV>` Implies that an ID, or OD Groove Cycle format block is output.
`IS-CCF-SEG`	For use with User-Defined Features and Part Handling features that use the call custom format technique to invoke a custom format in the post. It is valid in the Tool Change and Segment Start formats to indicate that the operation is using a custom format.
`IS-CUTOFF-XFER`	Specifies whether the current transfer operation includes a cutoff operation. See also `<CUTOFF-TOOL>`.
`IS-FIRST-OP`	`TRUE` if this is the first operation in the program.
`IS-LAST-OP`	`TRUE` if this is the last operation in the program.
`IS-METRIC`	`TRUE` if the NC code is in metric units.
`IS-OP-STOP`	Valid in the Program Stop format and indicates whether it is an optional stop. This format is called when a turn part is programmed to machine the main spindle side, output a program stop, the user manually removes the part and flips it around, and then machines the second Setup on the main spindle side. The value is set to `FALSE` in this case.
`JAWS-ONLY`	For use with the Support On and Support Off part handling features. `TRUE` if the steady rest jaws are opened or closed without moving the steady rest.
`LAST-TOOL`	`TRUE` if the current tool is the last tool in the program.
`LEAVE-SUP`	`TRUE` if the Leave Supported option is selected for a Part Handling feature.
`LEFT-HANDED`	`TRUE` if the current tool is left-handed.
`LINE-IS-SYNCED`	`TRUE` if at a sync point in Program Start, Tool Change, Segment Start, or Sync Point. Also returns `TRUE` when needed during pinch turning.
`MAIN-SPCMD`	Valid only in the spindle transfer formats (Spindle Open, Spindle Position, and so on). If true, M codes in the transfer format should be issued for the main spindle, otherwise use M codes for the sub spindle.
`MAIN-SPNDLE`	`TRUE` if the current operation is working on the main spindle, `FALSE` if on the sub spindle. Note: This word should not be used in the spindle transfer formats (see `<MAIN-SPCMD>`)
`OD`	`TRUE` for Outside Diameter operations.
`OFFSET-CH`	Normally used in a Segment Start block; `TRUE` if the `<OFFSET-NUM>` is changed between segments: `<IF><OFFSET-CH><THEN>` `{N<SEQ>}T{<COMP-NUM>}<TOOL>` `<OFFSET-NUM><EOB>` `<ENDIF>` This value may also be true in the Rapid Move format for the finish pass of a Groove feature if you have specified a second offset register.
`PART-CATCH`	`TRUE` if the Part Catcher option is enabled for a Part Handling feature in FeatureCAM.
`POS-DIR`	`TRUE` if the operation is cutting in a positive direction.
`POST-RCAN`	`TRUE` for the moves after a Rough canned cycle.
`PRE-GCAN`	`TRUE` for the last move before a Groove canned cycle.
`PRE-PCAN`	`TRUE` for the moves before a Finish canned cycle.
`PRE-RCAN`	`TRUE` for the moves before a Rough canned cycle.
`PUSH-PRESS`	`TRUE` if the Push/Press option is enabled for a Part Handling feature.
`RANGE-CH`	Normally used in a Segment Start block, and is `TRUE` if there is a change in gear range: `<IF><RANGE-CH><THEN>` `{N<SEQ>}MO5<EOB>` `{N<SEQ>}<SP-RANGE><EOB>` `{N<SEQ>}S<CALC-SPEED><SPINDLE><EOB>` `<ENDIF>`
`REUSE-PATH`	`TRUE` if the Reuse path in Canned cycle option is enabled in Turn properties.
`RIGID-TAP`	`TRUE` if Tap cycle is set to Rigid in FeatureCAM.
`SPNDLEPRESS`	`TRUE` when Use Push/Press function is selected on the Position the spindle page of the Sub-spindle transfer feature. On those machines with this option, it serves to apply pressure on the part by having the sub push the part into the Main spindle jaws, thus seating the part more accurately into the sub-spindle jaws during transfer.
`SW-USE-TOOL-Z`	`TRUE` if the current operation has Tool Z selected on the Tool Usage tab.
`TAPER`	`TRUE` for tapered threads.
`TCAN-CYCLE`	`TRUE` if inside a turning canned cycle.
`TCAN-END`	`TRUE` for the last move in the profile.
`TCAN-START`	`TRUE` for the first move in the profile.
`TH-ATSUBPOS`	`TRUE` if turret home format is called because of sub-spindle position where sub-spindle is moving closer to the main spindle.
`TH-ATTOOLCH`	`TRUE` if turret home format is called because of tool change.
`TOOL-LEFT`	`TRUE` if the tool is on the left of the cutting path.
`TP1-USE-TOOL-Z` through `TP4-USE-TOOL-Z`	`TRUE` if the first operation on the given tool post after the current sync point has Tool Z selected on the Tool Usage tab.
`UNDER-CHECK`	`TRUE` if the Undercut Check option is enabled in Turn properties.
`XFER-CW-SPINDLE`	Whether the spindle is rotating clockwise during the transfer.
