SRT( )

Sort String

Formats

1.	Sort Equal Length Elements:	SRT(string$,fixed_len[,ERR=stmtref])
2.	Sort Delimited Elements:	SRT(string$[,dlm_char$][,ERR=stmtref])

Where:

dlm_char$	Delimiter for each string element. If omitted, the default delimiter is the SEP character (e.g. $8A$).
fixed_len	Numeric expression. Length of each element in the string (all the same fixed length).
stmtref	Program line number or statement label to which to transfer control.
string$	String to be sorted.

Description

The SRT( ) function returns a sorted character string. The string elements are internally sorted into ascending sequence. The order of duplicate elements is undefined.

Note:
To sort a string into descending order, use the NOT( ) function to invert the bits in the string prior to and after sorting. See NOT( ) Invert String Bits/Logical Condition.

Format 1

Sort Equal Length Elements

SRT(string$,fixed_len[,ERR=stmtref])

If each element in the string is the same fixed length, use this format to sort the string.

Example:

rem To sort in ascending order:
     A$="0231405242670291234403242"
     print srt(A$,5)

->run
0231403242052421234467029

rem To sort in descending order:
     print not(srt(not(A$),5))

->run
6702912344052420324202314

Format 2

Sort Delimited Elements

SRT(string$[,dlm_char$][,ERR=stmtref])

If each element in the string has a delimiter or SEP character, use this format to sort the string. PxPlus considers the first character of dlm_char$ to be your delimiter. The default is the current SEP value.
