This source file ea.htm
contains an object Ea which represents the executable file
euroasm.exe
. It provides initialization of €ASM and assembles all source files
specified at cmdline.
As there is only one instance of EA, the object Ea is defined statically.

ea HEAD ; Start of module interface.
%EaStackSize %SETA 1M ; €ASM machine stack ES:ESP reserved size.
; Fatal error is thrown on overflow.
%EaPoolSize %SETA 64K ; Initial POOL block brutto size.
; More blocks may be allocated on demand later.
%EaBufferSize %SETA 4K ; Initial BUFFER brutto size.
; It can be increased (doubled) on demand when underestimated.
%EaStackDepth %SETA 16 ; Initial number of stackable objects on STACK.
; It can be increased (doubled) on demand when underestimated.
Ea.TimeStart keeps the real system time when euroasm.exelaunched. It is used to compute the duration of runtime, which will be reported with I0980. See also
Ea.Eaopt.TimeStamp.
Ea.BufferStack is a pointer to
STACK which stacks QWORDS which containEa.StackBottom is computed from Ea.StackOrg
decreased by the reserved stack size minus some safety reserve.
It is used for protection from stack overflow.

Semiinline macros hired in EuroAssembler are for the first time dummy-expanded
here in the module ea.htm
. Their @RTprocedures are declared as PUBLIC
in this module and they are declared as EXTERN in all other modules.
This prevents the runtime code from being repeatedly emitted in each separately assembled module, which would unnecessarily blow up the final PE size.
