Commands and Functions M-Q
MID()
The syntax of this function is
MID (string, start, [len])
The first argument is a string. The second argument indicates where to start the string extraction. The third
(optional) argument indicates how many characters to extract. If the third argument is omitted, the entire
string is extracted. In this example, the string "middle" is assigned to the variable var_string. Example:
var_string = MID("The middle string",5,6) yields
var_string = middle
MINUTE()
This function converts the real argument to a minute value. If there is no argument, it returns the current
minute (in local Impact device time). Example:
thisminute = MINUTE yields thisminute = 54
MKDIR
(CPM Only) This function creates a directory from a string expression. In this example, the directory "mydi-
rectory" is created in the current directory.
mkdir "/mydirectory"

page 5-4.
MONTH
This function converts the real argument to a month value. If there is no argument, it returns the current
month (in local Impact device time). Example:
thismonth = MONTH yields thismonth = 2
