Search for character/string in the string (INDEX, RINDEX, MINDEX, MATCH)

Function
This functionality searches for single characters or a string within a string. The function results
specify where the character/string is positioned in the string that has been searched.
Syntax
INT_ERG=INDEX(STRING,CHAR) ; Result type: INT
INT_ERG=RINDEX(STRING,CHAR) ; Result type: INT
INT_ERG=MINDEX(STRING,STRING) ; Result type: INT
INT_ERG=MATCH(STRING,STRING) ; Result type: INT
Semantics
Search functions: It supplies the position in the string (fist parameter) where the search has
been successful. If the character/string cannot be found, then the value -1 is returned. The
first character has position 0.
Significance
INDEX:
RINDEX:
MINDEX:
MATCH:
This allows strings to be broken up according to certain criteria, for example, at positions with
blanks or path separators ("/").
Example
Breaking up an input into path and block names
Program code
DEF INT PFADIDX, PROGIDX
DEF STRING[26] INPUT
DEF INT LISTIDX
INPUT = "/_N_MPF_DIR/_N_EXECUTE_MPF"
LISTIDX = MINDEX (INPUT, "M,N,O,P") + 1
