In gambas 2.7.0 appears Illegal instruction in the call of function
TEF_inicia:
EXTERN TEF_inicia(Resultado AS Pointer, Funcao AS String, Valor AS String,
CuponFiscal AS String, DataFiscal AS String, Horario AS String, Operador AS
String, ParamAdic AS String) IN "libclisitef" EXEC
"IniciaFuncaoSiTefInterativoA"
PUBLIC SUB Main()
DIM la AS Pointer
DIM lala AS String
la = Alloc(4)
TEF_inicia(la, "000000", "{200,00}", "{12345}", "20080618", "100000",
"{MARCOS}", "{}") 'gambas say illegal instruction in this line
lala = StrPtr(la)
Free(la)
PRINT lala
Now is the call correct ?
Thanks so much for the help and sorry my poor english.
