Subprogram Variables
$LABINC |
Label increment amount Type: Numeric, Read/Write |
This variable holds the label number increment. This increment is added to the current label number after a label is output, in preparation for the next label to be output.
$LABNO |
Current label number Type: Numeric, Read/Write |
This variable contains the current label number to use if a label is required to be output. $LABNO is incremented by $LABINC immediately following the output of a label at the start or end of a repeat range. Care must be exercised when changing $LABNO to ensure that duplicate labels are not generated, since this condition is not diagnosed by the post-processor.
$SUBEXT |
Subprogram tape file extension Type: String, Read/Write |
This variable indicates the subprogram tape file extension to use for subsequent subprogram files. The default file extension for subprograms is tps.
$SUBLVL |
Current sub-level in subprogram Type: Numeric, Read-only |
This variable indicates the subprogram nest level. A value of 0 means that there is no subprogram active. A value of 1 is for the first call.
$SUBMOD |
Processing mode of the subprogram (0-5) Type: Numeric, Read-only |
This variable indicates the current subprogram processing mode, as follows:
- 0:
if no subprogram active
- 1:
if scanning subprogram and storing it in memory.
- 2:
if the subprogram is being output to the tape.
- 3:
if scanning the subprogram during call for status and time.
- 4:
if the subprogram is being emulated.
- 5:
if the repeat range subprogram is being emulated.
$SUBNAM |
Current subprogram name Type: String, Read-only |
This variable contains the current subprogram name or subprogram number in string format. It will be blank if a subprogram is not active.
$SUBNO |
Current subprogram number ($NULL:NA) Type: Numeric, Read-only |
This variable contains the current subprogram number. It will be $NULL if a subprogram is not active.
$SUBTYP |
Type of subprogram (0-4) Type: Numeric, Read-only |
This variable indicates the type of subprogram, as follows[1]:
- 0:
if no subprogram active
- 1:
this is a repeat range subprogram (type RANGE)
- 2:
this is a user subprogram (type CNC)
- 3:
this is a predefined NC control subprogram (type SYSTEM)
- 4:
this is an emulated subprogram (type INCLUD)
