How to assign a CHAR Array to a SIGNAL (64 Bits) in CAPL script (CANOE)

Question

How do I assign a CHAR ARRAY (8 Bytes) into a SIGNAL (64 Bits) in CAPL script ?

How is the mapping between a char array and a 64 bit integer supposed to look like? — MSpiller, Jan 27 '22 at 10:28

Convert array to 64-bit variable minding the endianness.

Here's an example code:

qword value;
value = 0;
for(i = 0; i < 8; i++)
{
    value = value | (qword)array[i] << (8* (7 - i));
}

Due to the fact the signals longer than 52 bits in CAPL may cause some data loss in order to assign the converted value by using raw64 property.
