[Gretl-users] Series in bundles

Hello everyone, I found this strange behaviour of series as values in bundles. Script is explanatory. <hansl> clear set verbose off nulldata 10 s1 = index % 2 ? 1 : NA bundle b = null b.s = s1 smpl 1 5 --permanent print s1 eval b.s series s2 = b.s </hansl> <output> gretl version 2022b Current session: 2022-08-13 06:01 ? clear ? set verbose off Full data range: 1 - 5 (n = 3) 1.00000       NA  1.00000       NA  1.00000       1.0000       1.0000       1.0000       1.0000       1.0000       0.0000 -3.7922e-270       0.0000       0.0000  1.3134e-311 Incompatible types in assignment: series = matrix Error executing script: halting </output> Values change at each run and if I use "print" instead of "eval" the output is <output> gretl version 2022b Current session: 2022-08-13 06:12 ? clear ? set verbose off Full data range: 1 - 5 (n = 3) 1.00000       NA  1.00000       NA  1.00000 variable 1 duplicated in the command list. Error executing script: halting </output> Am I doing something wrong? Regards Federico
