Punched Cards - GE 235 System Manual

WIZ works with both floating point and fixed point numbers and handles typical algebraic and
trigonometric problems quickly and easily.
Modification I permits use of paper tape a s well a s
punched cards.
Use of the optional AAU with the WIZ System significantly decreases the run
time of the object program.
GAP, THE GENERAL ASSEMBLY PROGRAM
The General Assembly Program allows the programmer to write instructions f o r the GE-235 com-
puter in symbolic notation rather than in the absolute code of the computer. Mnemonic codes f o r
each instruction a r e carefully chosen to provide significance to the user. Memory addresses may
be assigned by using decimal notation o r by using symbolic notation chosen for maximum con-
venience to the particular program o r programmer. To extend the use of the General Assembly
P r o g r a m the programmer can call on various subroutines (described below) a s required by the
program.
The General Assembly Program also provides facility f o r assembling of programs in
either absolute o r relocatable form.
A wide range of assembler (pseudo) operations a r e available a s follows:
ALF
The ALF is used to enter an alphanumeric constant in the program.
BSS
The BSS is used to reserve a block of memory storage.
DDC
This is used to enter a double-word decimal constant in the object program.
DEC
This i s used to enter a single-word decimal constant in the object program.
EJT
This operation causes the printer to slew the GAP listing paper to the top of the following
page.
END
The END ( ~ n d of Program) indicates the end of the program to be assembled.
EQO
P e r f o r m s the s a m e function a s the EQU operation but the operand i s assumed to be an
octal number.
EQU
Used to over-rule the normal memory assignment performed by the assembly program.
FDC
This is used to enter a floatingpointdecimal constant in the object program. If no binary
scale is specified, determines the binary scale and yields a normalized floating point
number.
LOC
This operation performs the same function a s the ORG operation but the contents a r e
assumed to be in octal form.
LST
This pseudo-operation may be used to s t a r t the listing again after i t has been suppressed
by the NLS.
MAL
This pseudo-operation can be used to specify from 1 to 9 words of alphanumeric constants
on one card.
NAL
This pseudo-instruction causes any A/N constant o r group of constants to be assembled in
the 2's complement form.
