which the minimum and maximum size
I1 that fits in? and an I2 and I4?
excuse the ignorance of the question, most do not understand it well.
N and U, where it is recommended to use one or the other?
N and U both have automatically saved the sign of positive and negative?
for decimal numbers, for example: 12.2 (123.44)
I should use N14 or U14? calculation as the format / size?
I thank you. and apologize for your questions.
I’m Cobol programmer and in cobol to me seems more straightforward this.
