The 4- to 7-word entry for each array or variable consists of the following items:
Word FORMATDATA Contents FORMATDATAX Contents
+--------------------+ +--------------------+
[0] | dataptr | | |
|--------------------| |-- dataptr --|
[1] | datatype | | |
|--------------------| |--------------------|
[2] | databytes | | datatype |
|--------------------| |--------------------|
[3] | dataoccurs | | databytes |
|--------------------| |--------------------|
[4] | nullptr (optional) | | dataoccurs |
+--------------------+ |--------------------|
[5] | |

dataptr
is the address of the array or variable. For FORMATDATA, dataptr is a byte

For FORMATDATAX,
dataptr is an extended address.
