The AUXFUN Command [MLEPC]

The AUXFUN command is used to output auxiliary function (M) codes directly to the tape file. GENER does not check to see if the codes are supported by the control. This command is valid for all machine types.

\textbf{AUXFUN / } \mathit{code} \;\; {\small \sim} \! \big[ ,\mathit{code} \,\big] \begin{bmatrix} ,\! \begin{array}{l} \textbf{NOW} \\ \textbf{NEXT} \\ \textbf{SAME} ,\mathit{register\_list} \end{array} \, \end{bmatrix}

The numeric value or values specified on the AUXFUN command will be output, in sequence, using auxiliary function codes (commonly the M register) to the tape file. GENER will only accept codes ranging from 0 through 999.9 inclusive. If one or more codes are invalid, the entire command is ignored.

If NOW is specified, GENER will break to a new tape block after each code is output. If NEXT is specified (the default), as many M codes as are permitted by the control will be output on each block.

For example, to output an M3 you can use:

AUXFUN/3

If SAME is specified, the output of the M codes will be deferred until a register is output to the current tape block that matches one of the listed registers. Matching registers can be defined by index number or string descriptor. The keyword XYZ can be specified in place of individual X, Y and Z axes registers. Axis specific keywords (see the table) can be specified in place of axis specific registers.

For example, to output an M3 on the next NC block containing an S register:

AUXFUN/3,SAME,'S'

M codes output by AUXFUN are subject to PPFUN modification (–9, –16, –18 and –19).
