When you download an assembly language program, it is stored among the other programs
as a
PRGM NAMES
menu item. You can:
♦
Transmit it using the TI

86 communication link (Chapter 18).
♦
Delete it using the
MEM DELETE:PRGM
screen (Chapter 17).
♦
Call it from another program as a subroutine (page 224).
To run an
assemblyProgramName
, the syntax is:
Asm(
assemblyProgramName
)
If you write an assembly language program, use the two instructions below from the
CATALOG
.
AsmComp(
AsciiAssemblyPrgmName
,
HexAssemblyPrgmName
)

and stores the hex version
AsmPrgm

entered as the first line of an assembly language program
Entering and Storing a String
A string is a sequence of characters that you enclose within quotation marks.
♦
A string defines characters to be displayed in a program.
♦
A string accepts input from the keyboard in a program.
To enter a string directly, the syntax is:
"
string
"
To concatenate (join together) two or more strings, use
\
. The syntax is:
"
stringA
"+"
stringB
"+"
stringC
"+
...
You do not use quotation
marks to enter a string name.
In concatenation, you can
substitute
stringName
for
any
"
string
" .
