Commands can be abbreviated with letters shown in boldface. Letters not printed in boldface can be left out, for example: “
OU
TPUT ON” = “OU ON”
As a rule, letters can be entered in upper or lower case.
Stringing commands together:
Several commands is a single data string must be separated by semicolons “;”, for example: “USET 12; ISET 8.5; OUTPUT ON”
Numeric parameter formats:
m,
n:
Whole number (integer)
v:
Whole number, fixed or floating decimal point number with or without exponent, for example:
“12.5”, “0012.5”, “1.25E1”, “+1.25 e+01”
