Decode String into Decimal Integer Set of Values

This Subprogram will attempt to decode the specified text string into a Set of Decimal Integer Values. No alternative syntaxes are allowed and thus Octal and Hexadecimal representations are not valid, unlike the case of UI_DECODE_INT_SET.

Short Name Calling Sequence

STATUS = UIDCDS(STRING,VALUES,VASIZE,NVALUE)

Long Name Calling Sequence

STATUS = UI_DECODE_DEC_SET(...)

Input Arguments

STRING (Character) Text String VASIZE (Integer) Maximum No. of Values

Output Arguments

VALUES (Integer Array) Decoded Values Array NVALUE (Integer) Decoded No. of Values

Function Value

UI__SUCCESS ) Success UISUCC )

UI__TRUNCATED ) Truncated UITRUN )

UI__ILLEGAL_SYNTAX ) Illegal Syntax UIILSY ) Note:

1. This Subprogram differs from UI_DECODE_DEC_LIST in not allowing for bounds specifications within the Set. UI_DECODE_DEC_LIST allows implied sequences denoted by lower and upper bounds whereas this Subprogram only allows for a sequence of enumerated decimal numbers.
2. The UI__ILLEGAL_SYNTAX Function Value will be returned if the text string does not conform to the correct Decimal Integer List syntax (see Notes for UI_GET_DEC_SET). No modification will be made to the default value in this case.
3. Unlike the other Decoding Subprograms UI_DECODE_DEC_SET does not accept any Defaults. If the string is null (all spaces) then NVALUE will be set to zero, indicating that no Elements are present.
4. All Errors are informational only, no Error Message will be issued.
5. Any leading or trailing spaces or tabs within STRING will be ignored.
6. See UI_GET_DEC_SET for further notes on Arguments.
