Miscellaneous Commands
Suppress characters
FB Suppress all occurrences of up to 15 different characters, starting at the 
current cursor position, as the cursor is advanced by other commands.  
When the FC command is encountered, the suppress function is 
terminated.  The cursor is not moved by the FB command.  
Syntax = FBnnxxyy . .zz where nn is a count of the number of 
suppressed characters in the list, and xxyy .. zz is the list of characters 
to be suppressed. 
Stop suppressing characters
FC Disables suppress filter and clear all suppressed characters.  
Syntax = 
FC.
Replace characters
E4 Replaces up to 15 characters in the output message, without moving 
the cursor.  Replacement continues until the E5 command is 
encountered.  
Syntax = E4nnxx

Stop replacing characters
E5 Terminates character replacement.  
Syntax = E5.
Compare characters
FE Compare the character in the current cursor position to the character 
“xx.”  If characters are equal, move the cursor forward one position.   
Syntax = FExx  
where xx stands for the comparison character’s hex 
value for its ASCII code.  
Refer to the ASCII Conversion Chart (Code Page 1252), beginning on 
page A-4 for decimal, hex and character codes.
Compare string
B2 Compare the string in the input message to the string “s.”  If the strings 
are equal, move the cursor forward past the end of the string.  Syntax 
= B2nnnnS  where nnnn is the string length (up to 9999), and S consists 
of the ASCII hex value of each character in the match string.  For 
example, B2000454657374 will compare the string at the current 
cursor position with the 4 character string “Test.” 
Refer to the ASCII Conversion Chart (Code Page 1252), beginning on 
page A-4 for decimal, hex and character codes.
Check for a number
EC Check to make sure there is an ASCII number at the current cursor 
position.  The format is aborted if the character is not numeric.
