PL/I to Java mapping

When you generate a XOM from a PL/I include file, the PL/I types are mapped to default Java™ types.

Not all PL/I types map to a Java type.

Numeric data mapping

The following table shows the base, scale, and precision of the PL/I coded arithmetic data type, and shows the corresponding PL/I usage and the Java type to which the PL/I data type maps.

Table 1. Coded arithmetic data type in PL/I and mapped Java type
Base	Scale	Precision (p,q)	Example	Java type
Decimal	Fixed	1<=p<=4	`fixed dec(4)`	short
		5<=p<=9	`fixed dec(9)`	int
		10<=p<=18	`fixed dec(18)`	long
		19<=p<=31	`fixed dec(20)`	BigInteger
		q != 0	`fixed dec(5,4)`	BigDecimal
	Float	1<=p<=6	`float dec(6)`	float
		7<=p<=16	`float dec(8)`	double
		17<=p	`float dec(20)`	double (extended floating-point)
Binary	Fixed	1<=p<=7 (signed) 1<=p<=8 (unsigned)	`fixed bin(6)` `fixed bin(8) unsigned`	byte
		8<=p<=15 (signed) 9<=p<=16 (unsigned)		short
		16<=p<=31 (signed) 17<=p<=32 (unsigned)		int
		32<=p<=63 (singed) 33<=p<=64 (unsigned)		long
		q != 0	`fixed bin(8,2)`	BigDecimal
	Float	1<=p<=21	`float bin(16)`	float
		22<=p<=53	`float bin(32)`	double
		54<=p	`float bin(64)`	double (extended floating-point)

The following table shows picture strings of the PL/I numeric picture data type and the corresponding PL/I usage, and shows the Java type to which the PL/I data type maps. The PL/I management supports the picture format only with 'S', '9', and 'V.'

Table 2. Numeric picture data type in PL/I and mapped Java type
Picture string	Example	Java type
s9 - s(4)9	`picture s(4)9`	short
s(5)9 - s(9)9	`picture s(8)9`	int
s(10)9 - s(18)9	`picture s(10)9`	long
s(19)9 - s(31)9	`picture s(20)9`	BigInteger
v	`picture s9v9`	BigDecimal

String data mapping

The following PL/I string data attributes are supported:

CHARACTER, GRAPHIC, and WIDECHAR
NONVARYING, VARYING, and VARYINGZ
PICTURE

For the character pictured data, the PL/I management supports the picture format only with 'X', 'A', and '9.'

The following example shows the picture format using 'X', 'A', and '9':

declare 05 PartID picture 'AAA99X';

Note:

Variable-length strings are not supported. For example:

char(m)

Variable-length strings with REFER options can support only simple REFER usage. For more information about limitations on using the REFER option, see PL/I Limitations.
