OK, I have come up with a way to reproduce this. This is a simplified
version of a program started to fail, and when I try to )SIC after the
error, I get the error.
To reproduce, first define the following operator:
∇(OP rep) N;ct
ct←0
Lnext:
→(ct=N)/0
⊣OP ⎕IO+ct
ct←ct+1
→Lnext
∇
Then, define some dummy values:
* next ← {⍵}*
* V←1*
Then run the following:
*{disp ← '.#'[⎕IO+V←next V ⊣ ⎕DL ÷20]} rep 10*
SYNTAX ERROR
rep[1] ct←0
^
Run )SIC to clear the stack and try again:
*)SIC*
{disp ← '.#'[⎕IO+V←next V ⊣ ⎕DL ÷20]} rep 10
SYNTAX ERROR
rep[1] ct←0
^
Finally, run )SIC again, and the error is seen:
*)SIC*
