Considerations
• A passed P-relative iformat array must be in the same code segment as the call.
• variable-list array form
The four- to seven-word entry for each array or variable consists of these items:
Word FORMATDATA Contents FORMATDATAX Contents
+--------------------+ +----------------------+
[0] | dataptr | | |
---------------------| |- dataptr -|
[1] | datatype | | |
---------------------| |----------------------|
[2] | databytes | | datatype |
|--------------------| |----------------------|
[3] | dataoccurs | | databytes |
|--------------------| |----------------------|
[4] | nullptr (optional)| | dataoccurs |
+--------------------+ |----------------------|
[5] | |
|- nullptr (optional) -|
[6] | |
+----------------------+
dataptr
is the address of the array or variable. For FORMATDATA, dataptr is a byte address
for data types 0, 1, 12-15, and 17, and is a word address for other types. For
FORMATDATAX, dataptr is an extended address.
datatype
is the type and scale factor of the element:
