			The '''UDim(A$,X)''' [[internal function]] returns the number of rows in the array if X=1. Returns the number of columns in the array if X=2. Returns the current size of dimensions 3, 4, 5, 6 or 7 when X is 3, 4, 5, 6 or 7. If the optional parameter X is omitted, UDIM returns the size of the first dimension.

UDim(array-name[,X])

The '''UDim''' [[internal function]] returns the number of rows in the array if X=1. Returns the number of columns in the array if X=2. Returns the current size of dimensions 3, 4, 5, 6 or 7 when X is 3, 4, 5, 6 or 7. If the optional parameter X is omitted, UDIM returns the size of the first dimension.

====Comments and Examples====
00010 DIM A(15,20)
00020 PRINT UDIM(A), UDIM(A,1), UDIM(A,2)
00030 FOR I = 1 TO UDIM(A)
00040 FOR J = 1 TO UDIM(A,2)
00050 LET A(I,J) = I + J
00060 NEXT I
00070 NEXT J

The three numbers printed in line 20 will be 15, 15 and 20. Notice that by using UDIM in lines 30 and 40 this program can be changed to use a different sized two-dimensional array; the only programming change would be to change the dimensions in line 10 (or the array could be redimensioned using the MAT statement).

====Related Functions====
Other functions that operate on arrays are [[AIdx]], [[DIdx]], [[Srch]], and [[Sum]].
