2	Numeric	Optional	Maximum number of integers allowed Range: 0 - 63 Default: 15	1	3	0	0
3	Numeric	Optional	Maximum number of decimals allowed Range: 0 - 63 Default: 9	1	3	0	0
4	Alpha	Optional	List of allowable characters to be ignored e.g. $, %, C, R	1	50

Return Values:

Number	Type	Required or Optional	Description	Minimum Length	Maximum Length	Minimum Decimals	Maximum Decimals
1	Numeric	Required	Return integer portion	1	Unlimited	0	0
2	Numeric	Optional	Return decimal portion	1	Unlimited	1	Unlimited

RDML Example:
To get a packed decimal 9,2 result field #P92 from an alphanumeric field #A using 2 intermediate work fields called #P90 and #DEC.
DEFINE FIELD(#P92) TYPE(*DEC) LENGTH(9) DECIMALS(2)
DEFINE FIELD(#P90) TYPE(*DEC) LENGTH(9) DECIMALS(0)
DEFINE FIELD(#DEC) TYPE(*DEC) LENGTH(2) DECIMALS(2)
...
USE BUILTIN(CHECKNUMERIC)WITH_ARGS(#A72) TO_GET(#P90#DEC)
CHANGE FIELD(#P92)TO('#P90+#DEC')
