CABSAD$, CRELAD$–Addressing Routines
func-code
The function code determines which of the absolute addressing routines is called by
C$ABSAD. The function codes are described in the sections explaining each of the
functions. The function code must be enclosed by apostrophes.
The only values allowed for the function code on the C$ABSAD procedure call are
CABSAD$, CAINIT$, CBX$, CSX$, and CSYMVL$. Any other value entered for the
function code parameter on the C$ABSAD procedure call causes MASM to generate
an E flag on that line and print the error message.
p1,p2,p3
ILLEGAL C$ABSAD FUNCTION
The use of these parameters depends on the particular routine being called by
C$ABSAD. Some of the routines use only p1; some may use only p1 and p2. In
general, these parameters may be omitted. If so, the calling procedure uses the
values in specific registers for the values of these parameters. Each routine's
subsection describes these parameters.
pkt-addr
Address of the 300-word packet required by the common bank version of the
routines. If this parameter is omitted and the common bank version of the routine is
called (parameter t set to 'A' or 'CB'), then the address in register A5 is used as the
starting address of the packet. This parameter may be omitted if the call is to the
relocatable version of the routines but including it does not cause any problems.
6.1.1. CABSAD$–Compute Absolute Address
CABSAD$ computes the absolute address for a given address relative to a location
counter.
Calling Format
C$ABSAD[,t] ‘CABSAD$’[,rel-addr,lc,elt-name] [pkt-addr]
error return
normal return
Parameters
t
See 6.1.
CABSAD$
CABSAD$ is the function code that determines which of the absolute addressing
routines is called by C$ABSAD. It must be enclosed by apostrophes.
