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:

Response from command MG len6 {S4}

Response from command MG len5 {S4}

Response from command MG len4 {S4}

Response from command MG len3 {S4}

Response from command MG len2 {S4}

Response from command MG len1 {S4}
