CONWRD$–Condition Word Routine
Parameters
t
func
The type of call to CONWRD$. This parameter is optional and may be omitted. If CB
or A is specified, it must be enclosed by apostrophes.
blank
'CB'
'A'
Call the relocatable version of CONWRD$. This is the default if t is omitted.
Call the common bank version of CONWRD$.
Call the common banked version of CONWRD$ using the Auto Switch method.
The function for CONWRD$ to perform; it must be enclosed by apostrophes.
'SET27$'
Set bit 8 of the condition word; if bit 8 was already set, then set bit 7.
'CLEAR27$'
Clear bit 8 of the condition word; bit 7 is not changed.
Note: The names SET27 and CLEAR27 may appear to be unusual names for these
functions. The reason for this is that they were named when a different numbering
convention for bit positions was being used. Bit position 27 in the old convention
corresponds to bit position 8 in the current convention.
Example
The following example calls CONWRD$ from a MASM routine.
1. $(1)
2. START
.
.
.
3. C$ONWRD ‘SET27$’ . Set bit 8 of the condition word
.
.
4. C$ONWRD,’CB’ ‘CLEAR27$’ . Clear bit 8
In this example, line 3 calls the relocatable version of CONWRD$ to set bit 8 of the
condition word. Line 4 calls the common bank version of CONWRD$ to clear bit 8 of the
condition word.
