Dear Forum,
I am getting a syntax error when copy-and-paste
this simple program in a newly opened GAP session.
----------------------------
q:=true;
while q do
m:=2;
q:=First(Primes,s->s=m)<>2;
od;
----------------------------
The error is as follows:
---------------------------------------------
gap> q:=true;
true
gap> while q do
> m:=2;
> q:=First(Primes,s->s=m)<>2;
Syntax error: warning: unbound global variable
q:=First(Primes,s->s=m)<>2;
^
> od;
----------------------------------------------
Yet "m" appears to be a global variable afterwards:
-------
gap> m;
2
gap>
-------
On the other hand, a similar program (in which the variable "m"
is also defined for the first time within the while loop) runs fine:
---------------
gap> q:=true;
true
gap> while q do
> m:=2;
> q:=m<>2;
> od;
gap>
---------------
Could this be another bug?
