Dear All,

I use Maple T.A. 10. I try to use StringTools[Search] in algorithm variables but have not succeeded. Any help would be appreciated.

Algorithm Variable definitions


give us the following result, whereas I expect the return value 1.

pattern1 "sin(1/2*Pi)"
text1 "sin(1/2*Pi)"
test1 com.maplesoft.server.router.MapleSyntaxException: on line 116, syntax error, `,` unexpected:

I confirmed that one can use StringTools[Search] in the question source code as explained in

maple=evalb(0=StringTools[Search]("factor","$RESPONSE")) and evalb($RESPONSE=factor(x^2-1))

I note that searchtext or SearchText procedures could be used instead in algorithm variables.
