Using a Peripheral Communication Module
Appendix A
AĆ3
If you use the function abbreviations for report generation on your
1775-S4B scanner, note that GA Basic uses the following function
abbreviations:
Function Name GA Basic Abbreviation
From_bcd
Getchar
Testchar
Testline
To_bcd FR
G
TESTC
TESTL
TO
When you are specifying an octal address for a word or bit, you must enter
leading zeros for the file, word, and bit for the operation to function
properly in GA Basic. For example:
Address Description
$B01:05/012 The address would correspond to binary file 1, word 5, bit 10
(decimal). Octal addressing for 1775ĆS4B report generation is
discussed in chapter 6.
When you are using the.EQ. expression operator, enter spaces before and
after the operator. For example:
If you enter:
IF (A .EQ. 10) GO LOOP
The peripheral communication module jumps to the label LOOP if user A
is equal to 10. Without the leading and trailing spaces around the .EQ.
operation, the module generates an error code.
When you are formatting data, the minimum format that the peripheral
communication module accepts is a base modifier. Otherwise, your
procedure generates an error. For example:
If you enter:
P A!016B
The formatted statement above would be valid for GA Basic. The
peripheral communication module prints user symbol A in 16-bit binary.
