Re: RPGLE pgm to parse a string -- RPG400-L

Sorry if i have trobuled u

 thing is that i want to get 'my' from 'this_is_my_test_string'

where everything could be varible except the fact that varible i want to
extract comes b/w second from  last and third from last   '_',

i hope u  clear with it, from my analisis what i found is

1)  there r very few operators/built in functions which could help me while
i come from right to left,
2) going from left to right i cant determine where the string comes( i need
2 pass for that)
   i think this results in more computation

thats why i asked for alternative
