● "x" stands for the number of the GUD in the DEF file.
● "A1" stands for the maximum index of dimension 1.
● "A2" stands for the maximum index of dimension 2.
For additional information on converting or linearizing GUD arrays, please refer to the
following sections:
● Linearization based on the sorting in SINUMERIK Operate (Page 78)
● Converting a three-dimensional GUD array for linear access (Page 79)
Example
Linearizing a two-dimensional array, e.g. [2,3] looks like this:
Table 6- 4
Two-dimensional index in the NC
0 0
0 1
0 2
1 0
1 1
1 2
The example is two-dimensional and has three elements in each dimension.

● GUD definition: DEF {NCK|CHAN} type Name[number of lines, number of columns]
● "x" stands for the number of the GUD in the DEF file.
