Subject: Three Questions: Allocated, Memory, and C Functions/Porting to PC
Errors-To: icon-group-errors@cs.arizona.edu
Some questions from a novice Icon user....
1. Does anyone have any example programs using the &allocated keyword?
From the documentation, I thought it would return 4 values, but
I am only getting one on the DECstation and the Alpha using
Icon 9.
2. I have an Icon program that must process input character by character for
tokenizing. This creates a lot of garbage, slowing things down considerably.
Is there any way to manage some memory directly in conjunction with
the garbage collector? Or are there any hints for efficent use of Icon
on a character by character basis?
3. One way around #2 above may be to use a C function. Can C functions be
linked in with the PC version? Does anyone have any experience doing
this and supporting the feature under both Unix and DOS?
Thanks, Gail.
