Checksum can be used to compute a separate value for
different part of an executable file.
Checksum/file (default) creates a symbol with the result.
Examples of both follow:
     
$checksum/image tab.exe
file USER2:[VOAOP.ALOK]TAB.EXE;1
image section %D'1' checksum is %X'69211A27'
image section %D'2' checksum is %X'270DC263'
image section %D'3' checksum is %X'E23A9D20'
image section %D'4' checksum is %X'7ED61A58'
image section %D'5' checksum is %X'100B731B'
image header checksum is %X'3CBF990A'
checksum of all image sections is %X'C2CB2C27'
     
$checksum tab.exe
$show symbol checksum$checksum
  CHECKSUM$CHECKSUM = "826517707"
