different behaviour between IDL and GDL in formatted output #1138

brandy125 commented 3 years ago

GDL writes an additional comma at the end if the output is only a single number.

IDL> print,String(FORMAT = '(1(I1, :, ", "))', [1,1])
1,  1
IDL> print,String(FORMAT = '(1(I1, :, ", "))', [1])
1

GDL> print,String(FORMAT = '(1(I1, :, ", "))', [1,1])
1,  1
GDL> print,String(FORMAT = '(1(I1, :, ", "))', [1])
1,
