Amiga

This page is about the so called 'classic Amiga' version of Free Pascal, which means Motorola 680x0 CPU based systems running AmigaOS 3.x and below. For MorphOS and AmigaOS4 versions, see the relevant pages.

Stack

Under Amiga, the default stack is set to 256 kB. Stack size can be set directly by the programmer with a compiler switch (-Cs), or with the {$MEMORY} directive. The memory area for the stack is dynamically allocated on program startup, so if you set this value too high, in low memory situations your program may exit immediately on startup without any further notice.

Please note that increasing stack size with the 'stack' utility will *NOT* work for your app, because the RTL startup code will replace the existing stack with the size specified by the directive, using the exec.library/StackSwap function.
