Examples of STACK Statements

track of the size and data type of stacked values. It loads byte values in bits <8:15>

and a 0 in bits <0:7>.

Modularize any use of STACK statements as much as possible; they are not portable

to future software platforms.

Examples of STACK Statements

This example loads values of various data types onto the register stack:

STORE Statement

The STORE statement removes values from the register stack and stores them into

variables.

variable

is the identifier of a variable—a simple variable, array element, simple pointer, or

structure data item—with or without a bit deposit field and/or index. To update the

content of a simple pointer, prefix the pointer identifier with @. If you list multiple

identifiers, storage begins with the leftmost identifier.

Usage Considerations

The data type of each variable specified dictates the number of registers to unload,

starting at the current setting of the RP. If the RP setting is too small to satisfy the

variable data type, the compiler removes the required number of items from the data

stack, places them on the register stack, and stores them in the variable.
