Explain about REXX
POS : return the position of one string str1 into str2- start from by default position 1
INDEX : returns the character position of one string, needle, in another, haystack, or returns 0 if the string needle is not found or is a null string.
By default the search starts at the first character of haystack (start has the value 1).
You can override this by specifying a different start point, which must be a positive whole number.
LASTPOS :returns the position of the last occurrence of one string, needle, in another, haystack
pos----- string
index---character
Lastpos-last occurence of one string into another
