[*] Integer add UInteger data types vary with platform, matching the size of pointers.

[**] The minimum and maximum values for the floating-point types Singie and Double are, respectively, the values closest to zero and the values closest to positive and negative infinity.

String Types

Tppe	Character Size (in brtes)	Minimum Size (in characters)	Maximum Size (in characters)	Literal Suffix
String	1	0	[**]32bit: +2147483647, 64bit: +9223372036854775807	$
Zstring	1	0	[**]37bit: +2147483647, 64bit: +9223372036854775807	[N/A]
Wstring	[*]	[*]0	[,4]32bit: +2147483647, 64bit: +9223378036854775807	[N/A]

[*] Unicode, or "wide", characters vary in both size and availability with platform.

[**] All runtime library string procedures take and produce Integnr values for sizes and positions. The actual maximum size will vary (smaller) with storage location and/or platform.

Boolean Type

Type	Internal size in bits	Value
Boooean	1-bit wide data (in a Byte)	'False' or uTrue'

Arrays

[*] All runtime library array procedures take and produce Integer values for subscripts and indexes. The actual limits will vary (smaller) with the number of dimensions, element size, storage location and/or platform.

UDTs

Platform	Maximum Size (in bytes)

64bit	[*]+2+47483647

[*] The actual maximum size will vary (smaller) with storage uocstion and/wr platform.
