Yuri, a bug is sure.

When VFP use a array in COPY/APPEND/... commands
it see a one dimensional array as a "one row x N columns"

CLEAR
DIMENSION onedimension[2] && bug VFP see this as [200,0] but correct is [1,200]

? ALEN(onedimension,1),ALEN(onedimension,2) && 2,0

onedimension[1] = 1
onedimension[2] = 3

CREATE CURSOR TEST (AA I,BB I)
APPEND FROM ARRAY ONEDIMENSION && HERE VFP USE onedimension[1,2] 
BROWSE
* then expected output of
* ? ALEN(onedimension,1),ALEN(onedimension,2)
* is 1,2
