5 IMPLICIT CHARACTER*5 (h-z)
9 parameter(bad="a", good="(a)")
11 PRINT ('a'), "hello" ! { dg-error "Missing leading left parenthesis in format string" }
12 WRITE (*, ("a")) "error" ! { dg-error "Missing leading left parenthesis in format string" }
14 PRINT 'a', "hello" ! { dg-error "Missing leading left parenthesis in format string" }
15 WRITE (*, "a") "error" ! { dg-error "Missing leading left parenthesis in format string" }
16 WRITE (*, bad) "error" ! { dg-error "Missing leading left parenthesis in format string" }
18 PRINT 'a' // ', a', "err", "or" ! { dg-error "Missing leading left parenthesis in format string" }
20 PRINT '(' // 'a' ! { dg-error "Unexpected end of format string in format string" }
22 ! the following are ok
23 PRINT "(2f5.3)", bar, foo
25 WRITE (*, " ((a))") "hello"
26 print "(a" // ")", "all is fine"
29 ! verify that we haven't broken non-constant expressions
33 print implicitly_typed, "something"
34 write (*, implicitly_typed_as_well) "something else"
