FPS System Routines
The OP registers are used extensively by the system’s FPS routines for input and
output.
FPS Allocation Routines
These routines are separated by either the size of the allocation or by a Data Type of a
value, Real/Complex.
• Pushes nine bytes onto the FPS. For these routines, the word Real implies nine
bytes.
PushReal
Pushes nine bytes pointed to by HL onto the FPS.
PushRealO1
Allocates nine bytes on FPS then OP1 is copied to FPST.
PushRealO2
Allocates nine bytes on FPS then OP2 is copied to FPST.
PushRealO3
Allocates nine bytes on FPS then OP3 is copied to FPST.
PushRealO4
Allocates nine bytes on FPS then OP4 is copied to FPST.
PushRealO5
Allocates nine bytes on FPS then OP5 is copied to FPST.
PushRealO6
Allocates nine bytes on FPS then OP6 is copied to FPST.
• Pushes a complex number from two consecutive OP registers onto the FPS.
For these routines, the REAL part of the complex number is in the OP register
specified and the IMAGINARY part is in the following OP register. Only nine bytes of
each of the registers are pushed onto the FPS.
PushMCplxO1
Pushes OP1 onto FPS then pushes OP2 onto FPS. FPS1 = OP1,
FPST = OP2.
PushMCplxO3
Pushes OP3 onto FPS then pushes OP4 onto FPS. FPS1 = OP3,
FPST = OP4.
• Checks the data type of a value in an OP register for either Real or Cplx, and
pushes the value onto the FPS.
These routines check the specified OP register’s data type byte, and if CplxObj, then
pushes a complex number from the OP registers in the same way as the
PushMCplx routines above. Otherwise, pushes nine bytes from the register
specified onto the FPS.
PushOP1
Pushes OP1 or OP1/OP2, checks OP1 = CplxObj.
PushOP3
Pushes OP3 or OP3/OP4, checks OP3 = CplxObj.
PushOP5
Pushes OP5 or OP5/OP6, checks OP5 = CplxObj.
