PS (PUSH)
Syntax:
M, I, O, T, C
Operands:
Action:
The PS command enables you to buffer data. The iTNC loads the addressed
operand onto the data stack. Because the data stack has a width of 32 bits,
you must write to it with a minimum width of one word. The iTNC copies the
operand value into bit 7 of the data stack's current address. The vacant bits of
the occupied memory remain undefined or unused. In the event of a stack
overflow, the iTNC outputs an error message.

PS (PUSH)
Syntax:

Operands:
Action:
The PS command enables you to buffer data. The iTNC copies the addressed
operand value into the current address of the data stack. During the word
processing, the iTNC copies two words per PS command onto the data stack
and extends the operand—in accordance with the MSB—with the correct
algebraic sign. In the event of a stack overflow, the iTNC displays an error
message.
