B4R Question String/variable handling guide

[pecket]

I would be so thankful if someone could demonstrate some variable/string handling. I'm having problems understanding the documentation when there are no actual examples there. For example:

• Reading a single (or multiple) byte(s) from a byte array, using it in an If- or Select-statement.
• Converting between types correctly.
• When you need to use rRandomAccessFile and so on.
• Binary comparison om single or multiple bytes in an array, string, numeric variable and stuff like that.

I tried to use the rRf24 library to communicate between a few Arduinos, but I keep messing up the string handling/conversions.

Simple examples covering other stuff, such as operators, Core functions etc would also be great. Since the footprint of B4R is a bit on the heavy side I prefer using less conversions etc when I can.

Best regards,
Peter

See these tutorials:
Memory, Variables and Objects
Strings and Bytes

Avoid using strings whenever possible. Use B4RSerializator to convert numbers and other types to an array of bytes: [B4X] B4RSerializator - Send and receive objects instead of bytes

I'll post my current project in the forum and ask for help. I can't seem to grasp how to properly convert between different types of variables, no matter how much I try. It just doesn't make sense to me.
