Galil DMC-13X8 Functions, ENTER,LENS6, Flen=@Fraclen, LEN1=FLEN&$00FF, Function Description

significant byte 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}
