[Info-vax] String Manipulation

[HCorte]

Have a string named MILLCON that contain "," as delimiter to split in two substrings have two aproches:

1º using routine ELEMENT from STR$

STR$ELEMENT(MESSCON,0,",",MILLCON)
STR$ELEMENT(IP_ADDRESS,1,",",MILLCON) 

2º using routine INDEX and LEN from LIB$

POS_AUX = LIB$INDEX(MILLCON,",")
MESSCON = MILLCON(1:POS_AUX-1)
IP_ADDRESS = MILLCON(POS_AUX+1:LIB$LEN(MILLCON)-(POS_AUX+1))

is either aproach good or is there one bether and if so why?
