Section 11. String Functions

SplitStr (ResultString, SearchString, FilterString, NumSplit, SplitOption)

The SplitStr instruction is used to return an array of strings or numerics from a

search string.

Syntax

SplitStr ( ResultString, SearchString, FilterString, NumSplit, SplitOption )

Remarks

The FilterString and SplitOption help to define the array returned by the

SplitStr instruction.

Parameter

& Data Type

Enter

SPLITSTR PARAMETERS

SplitResult

Var Arrayr

The SplitResult parameter is an array in which the split string will be stored.

SearchStr

String or Var

The string on which this instruction will operate.

FilterString

String or Var

Used to provide a filter for the string(s) to be returned. For a FilterString

using non-printable ASCII characters, use the CHR function and the

appropriate ASCII code

NumeSplit

Constant

Used to define the maximum number of strings or values returned by the

instruction.

SplitOption

Constant

The SplitOption parameter is a code used to specify the method of splitting

the string:

0 NUMERIC SearchString is parsed based upon the occurrence of a

number in the string (delimiters are + - . 0 1 2 3 4 5 6 7 8 9 0 E). The

numeric value is stored in the array; other characters are discarded. With

this option, FilterString is ignored.

1 NON-NUMERIC - SearchString is parsed based upon the occurrence of

non-numeric characters in the string (delimiters are any character but + -

. 0 1 2 3 4 5 6 7 8 9 0). The non-numeric characters are stored in the

array; numeric characters are discarded. FilterString is ignored.

2 SEARCHSTRING - SearchString is parsed based upon the occurrence

of the entire FilterString.

3 SEARCHCHARS - SearchString is parsed based upon each occurrence

of any character that is in FilterString

4 HEADERFILTER - Any strings succeeding FilterString are returned.

5 FOOTERFILTER - Any strings preceding FilterString are returned.

6 HEADERFILTERCHARS - Strings succeeding any character in the

FilterString char list are returned in SplitResult.

7 FOOTERFILTERCHARS - Strings preceding any character in the

FilterString char list are returned in SplitResult

8 NUMERICHEX - SearchString is parsed based upon the occurrence of

hexadecimal numerics in the string (delimiters are any character but 0 1

2 3 4 5 6 7 8 9 0 A B C D E F). The hexadecimal value is stored in the

array. With this option, FilterString is ignored.

here X is one of the options above, right justify the resultant a

ray,

filling vacant elements with NAN (if numeric) or a NULL string if a

string.
