Splits a string into an array of substrings called tokens.

string—The scalar string that is scanned and split into tokens.

pattern—A scalar string specifying a regular expression. This regular expression is the delimiter used to determine where to split the string.

tokens—A string array of substrings.

None.

STRSPLIT uses regular expressions, not wildcard characters, for pattern matching. To use STRSPLIT, it is crucial that you understand regular expressions. For a detailed discussion of regular expressions, see the PV‑WAVE Programmer’s Guide.

In this example, a string containing a colon (:) separated list of directories is split into a string array of directories.

path = '/bin:/usr/bin:/usr/local/bin:/etc:/usr/ucb/bin'

dirs = STRSPLIT(path, ':')

PRINT, dirs, Format='(A)'

; PV-WAVE prints the following:

; /bin

; /usr/bin

; /usr/local/bin

; /etc

; /usr/ucb/bin
