No doubt, these are most likely very important macro’s
sc_lin_cod_barra_arrecadacao
sc_lin_cod_barra_banco
sc_lin_digitavel_arrecadacao
sc_lin_digitavel_banco
They have something to do with barcodes, but I suggest you rename them to a valid English named macro or add English named synonyms for them.
Same goes for other portugues expressions like in variables.
