HIGH

Action

Retrieves the most significant byte of a variable.

Sets the most significant byte of a WORD variable.

Syntax

var = HIGH( s )

HIGH( s ) = value

Remarks

Var

The variable that is assigned with the MSB of var S.

The source variable to get the MSB from when used as a function.

The target variable to set the MSB when used in an assignment

value

The value to assign when used in an assignment.

When used in an assignment , only the second byte of the variable will be set. The intention purpose is to set the MSB of a WORD or INTEGER.

It will also work on a LONG or DWORD but it will set the second byte in memory which is not the MSB of a LONG/DWORD.

Also, this will work on arrays, but there is no type checking which means that you should not use this on a single BYTE since it could overwrite other memory.

In version 2083 the HIGH function can also be used to set the MSB of a variable. This for compatibility with BASCOM-8051.
