PUSH

Syntax: PUSH

expr1

expr2

,...]

Where:

expr

is a numeric value

Function: Puts the value of

expr

to the argument stack. The first value PUSHed and is the last POPped.

Mode: Command, run

Use: PUSH X,Y

DESCRIPTION

PUSH and POP instructions pass values to Basic subroutines. The last value pushed is the last expression in

the PUSH instruction, and is also the first popped off the stack. Multiple expressions can be pushed onto the

argument stack by separating the expressions with commas.

The PUSH and POP instructions alleviate some of the problems of global variables in Basic. They eliminate

the need to equate subroutine variables to global variables used by the program which called the subroutine.

POP, LD@, ST@

ERROR

A-STACK Attempt to push too many values on the argument stack. Typically no more than 32 values may

be PUSHed onto the stack before it is full.

EXAMPLE

Please refer to the POP example.

1 2 ... 49 50 51 52 53 54 55 56 57 58 59 ... 83 84
