It is, that's why I need to create a push & pop function by hand :) since I'm working in CQuote:

It is called push in most assembly languages, but you are using C.Quote:

when you using asm with c you do __asm{
or can you use push directly with it ?
The odds that we actually want to push on the system stack is very very very very very small. We want our own stack.Quote:

Also it is 'upside down' the 'top' of the stack is high and as you push stuff
onto it it is stored at lower memory locations.
Code:
PUSH B PUSH BC C5 (SP-2) <- C; (SP-1) <- B; SP <- SP - 2
PUSH D PUSH DE D5 (SP-2) <- E; (SP-1) <- D; SP <- SP - 2
PUSH H PUSH HL E5 (SP-2) <- L; (SP-1) <- H; SP <- SP - 2
PUSH PSW PUSH AF F5 (SP-2) <- Flags; (SP-1) <- A; SP <- SP - 2
--- PUSH IX DDE5 (SP-2) <- IXl; (SP-1) <- IXh; SP <- SP - 2
--- PUSH IY FDE5 (SP-2) <- IYl; (SP-1) <- IYh; SP <- SP - 2
POP B POP BC C1 B <- (SP+1); C <- (SP); SP <- SP + 2
POP D POP DE D1 D <- (SP+1); E <- (SP); SP <- SP + 2
POP H POP HL E1 H <- (SP+1); L <- (SP); SP <- SP + 2
POP PSW POP AF F1 A <- (SP+1); Flags <- (SP); SP <- SP + 2
It is, but it's been part of C since Turbo C/C++ 1.01, that I know of.
It is, except that here we are using terms that are similar thing only implementing them with C.Quote:

an arbitary name of a function.
