of the fraction.  The characters can be individually separated by using bit-wise operations as illustrated in the 
following example: 

#TEST 

Begin main program 

IN “ENTER”,LEN{S6} 

Input character string of up to 6 characters into variable ‘LEN’ 

FLEN=@FRAC[LEN] 

Define variable ‘FLEN’ as fractional part of variable ‘LEN’ 

FLEN=$10000*FLEN 

Shift FLEN by 32 bits (IE - convert fraction, FLEN, to integer) 

LEN1=(FLEN&$00FF) 

Mask top byte of FLEN and set this value to variable ‘LEN1’ 

LEN2=(FLEN&$FF00)/$100 Let 

variable, 

‘LEN2’ = top byte of FLEN 

LEN3=LEN&$000000FF 

Let variable, ‘LEN3’ = bottom byte of LEN 

LEN4=(LEN&$0000FF00)/$100 Let 

variable, 

‘LEN4’ = second byte of LEN 

LEN5=(LEN&$00FF0000)/$10000 Let 

variable, ‘LEN5’ = third byte of LEN 

LEN6=(LEN&$FF000000)/$1000000 Let 

variable, 

‘LEN6’ = fourth byte of LEN 

MG LEN6 {S4} 

Display ‘LEN6’ as string message of up to 4 chars 

MG LEN5 {S4} 

Display ‘LEN5’ as string message of up to 4 chars 

MG LEN4 {S4} 

Display ‘LEN4’ as string message of up to 4 chars 

MG LEN3 {S4} 

Display ‘LEN3’ as string message of up to 4 chars 

MG LEN2 {S4} 

Display ‘LEN2’ as string message of up to 4 chars 

MG LEN1 {S4} 

Display ‘LEN1’ as string message of up to 4 chars

This program will accept a string input of up to 6 characters, parse each character, and then display each character.  
Notice also that the values used for masking are represented in hexadecimal (as denoted by the preceding ‘$’).  For 
more information, see section Sending Messages. 

To illustrate further, if the user types in the string “TESTME” at the input prompt, the controller will respond with 
the following: 

T 

Response from command MG LEN6 {S4} 

E 

Response from command MG LEN5 {S4} 

S 

Response from command MG LEN4 {S4} 

T 

Response from command MG LEN3 {S4} 

M 

Response from command MG LEN2 {S4} 

E 

Response from command MG LEN1 {S4}
