While loop in rotary buffer

[wbzhong]

Hi, I am using the rotary buffer to run a large program file. I found the rotary buffer does not support while loop when initializing the buffer.

For example, run the scripts in the terminal:

&1 open prog 0
P0=0
while(P0<10){
P0+=1
}
close

PMAC reports "error #31: missing }: while(P0<10){"

However, the fixed buffer is fine.
