Action

Sets the available space for the frame.

 

 

Syntax

$FRAMESIZE = var

 

 

Remarks

 

While you can configure the Frame Size in Options, Compiler, Chip, it is good practice to put the value into your code. This way you do no need the cfg(configuration) file.

 

The $FRAMESIZE directive overrides the value from the IDE Options.

 

It is important that the $FRAMESIZE directive occurs in your main project file. It may not be included in an $include file as only the main file is parsed for $FRAMESIZE.

 

You need a minimum frame size of 24 bytes. This space is used by a number of routines. For example string<>numeric conversion routines. If you use Print numVar, then the numeric variable "numvar" is converted into a string representation of the binary number. The framespace buffer is used for that. While the framespace server as dynamic memory, a fixed address is used. For this reason the buffer has a fixed size of 24 bytes.
