## Explodex

### Format

stringarrayvariable$ = explodex ( string , regex )
arrayvariable$ = explodex ( string , regex )

### Description

Splits up string into substrings wherever the regular expression regex occurs. Substrings are stored in either the string or numeric array defined in the assignment statement. The array will be re-dimensioned to the exact size to store all of the substrings. Unlike ExPLODE, EXPLODEX allows ignoring specific variations (case sentive, spelling etc), see example below ”[Aa][Nn][Dd]”.

### Example

    # explode on regex //[,]* //
    a$ = "We all live in a yellow submarine, yellow submarine, yellow, submarine."
    w$ = explodex(a$,"[,]* ")
    for t = 0 to w$[?]-1
       print "w$["+t+"]=" + w$[t]
    next t

    # explode on regex //[Aa][Nn][Dd]//
    a$="1 and 2 AND 3 and 5 aND 99 AND 8.88 aNd 6.45"
    n = explodex(a$,"[Aa][Nn][Dd]")
    for t = 0 to n[?]-1
       print "n["+t+"]=" + n[t]
    next t

will display

    We all live in a yellow submarine.
    w$[0]=We
    w$[1]=all
    w$[2]=live
    w$[3]=in
    w$[4]=a
    w$[5]=yellow
    w$[6]=submarine
    w$[7]=yellow
    w$[8]=submarine
    w$[9]=yellow
    w$[10]=submarine.
    n[0]=1
    n[1]=2
    n[2]=3
    n[3]=5
    n[4]=99
    n[5]=8.88
    n[6]=6.45
