What do you do about overflow and underflow?

How did you handle number overflow and underflow?

Thanks everybody . I see the error. Lesson learned.

I am sorry I did not include some code that was needed. here is the corrected listing: Dim Parts as zstring*40 Dim a as zstring*2 Dim Bins(1 to 3) as string Parts = "" Print "enter staples" do a="" while a="" a=inkey wend print a; Parts = Parts + a loop while ...

Using this example: Dim Parts as zstring*40 Dim Bins(1 to 3) as string Parts = "staples" Bins(1) = Parts Bins(2) = ""staples" 'Notice the string length for Bins(1) <> Bins(2) 'Now any time Bins() is printed it will always have a additional byte. Is there a easy way to always...

Thank you for the information fxm. one question: 1. In my example a save the contents of the zstring to a dynamic string array. I want to use a pointer to access that same array. I saw no examples on how to have a pointer created to access the contents of a dynamic string array. How do I do this? Th...

Hello, I have read all of the documentation on using allocate/reallocate/deallocate for zstrings. I created a small test program to test my knowledge. From the results of my test program I saw no benefits in using the allocate/reallocate/deallocate for zstrings. I was under the assumption than if a ...

Thank you dodicat.
I did not know that was necessary.

I have created a small code example of a error I keep on getting when attempting to use byref to return 2 different parameters. Here is the code: declare sub ValidateLeadingSign(_ Digit as string,_ PlusExists as byte,_ MinusExists as byte) declare sub GetOperand() Dim shared TxtLine as ZString*513 '...

To anybody who can point me to a tutorial on how to create multiple files (modules) that you link together and become a freebasic program. I have separate subs and functions and global variables with global structures working as 1 BIG file but would link to know what to do to have them as separate m...

Thank you MrSwiss and fxm. That information helped a lot. I think I might have found a bug unless I need to do some more reading about zstrings. Dim UpperLabel as zstring*247 dim Text as zstring*1 Dim Index as uByte Dim AscChar as uByte dim Label as string Dim Text1 as string input "enter lower...

Thank you fxm.

Did not realize that string indexes started at 0 instead of 1.
Is there a document that covers using [] for strings?
I did not see one.

Does freebasic support this type of code: Dim shared UpperLabel as zstring*247 Dim STRChar as zstring*1 Dim Index as ubyte Dim KeyString as string do Input "my key word = ";STRChar UpperLabel[Index] = STRChar[1] print "UpperLabel ";UpperLabel print "UpperLabel length = "...

Here is the code I ended up using. It allows a Ulong value that is converted to a string by size in bytes. That means a number that is &h12345678 can be truncated to 2 or 1 byte by the size specified. I needed this for to make a string that is based on a register size or a ptr size of a memory a...

Thanks everybody for the explanation. Too bad this doesn't work in freebasic.
It would have been an easy way to dynamically type variables.
