How to handle with HMI I/O's while using F1616BA with 40/40 Extension cards ; as the inputs for HMI starts from 57-66 while the sample code starts from input  0.

Look for examples in the folder:

C:\TRiLOGI\TL6\usr\samples\HMI\HMI57to72.PC6

For other combinations you can modify based on the same knowledge as other files on the above folder.

Dear sir
I am using sample code for scaning HMI key pad with 40/40 extension card placed at
c:\trilogi\TL6\usr\samples\HMI\HMI57to72.pc6
i am trying to modify display string customise function as
a= val(z$)
if(a<=24)
setLCD 2,1,"command no. "+str$(a)+"  "
endif
if(a>24)
set LCD 3,1,"Wrong Command"
endif
z$=" "
the problem is even if condition no.2(a>24) gets false the LCD shows the same message
the note sticks on LCD
what should i do to get rid of this problem

of course, you didn't erase line 2. You simply added line 3.

How to erase HMI message once written.

You can either clear screen with SETLCD 0,0,CHR$(1)  or you can overwrite the existing lines with spaces.

E.g. define a variable E$ = "                    "  (20 spaces)

Then you can erase any line by:

   SETLCD 1,1, E$   ' erase line 1
   SETLCD 4,1, E$   ' erase line 4
