HI,
I trying to extract a variable string from a data structure like the following:
DTextDS DS Based(TextPtr)
D TextLen 1 2B
0
*TEXTData 3 3
Note that TEXTData is not even defined at this point.
What I know is the value of the Text Pointer and the length of the text
data (from TextLen). I am having a hard time trying to figure out how to
retrieve the text string from this structure into a variable character
field that I can work with. The TEXTData field should not even need to be
defined in the DS as long as I know the address where it starts and how
long it is. Compiler did not like %Subst(TextDS : 3 : TextLen) because 3
is larger than the defined DS.
I am just not seeing the solution to this. I am trying to do this without
having to specify a specific length to the TEXTData field or the DS. I was
thinking there must be some sort of C function that lets be extract from
memory into a string, but I haven't found it yet. Something like give me
the string at TextPtr + 2 for TextLen positions.
Suggestions?
Thanks
