The POSIT function finds the starting position of a substring within a larger string. For example, the starting position of the substring DUCT in the string PRODUCTION is 4. If the substring is not in the parent string, the function returns the value 0.
To use this function, you must import the function library MNTUWS. For information on importing this library see Accessing and Calling a Function.
There is also a POSIT function available for the reporting language. For information on this function, see POSIT: Finding the Beginning of a Substring.

MAINTAIN FILE movies Module Import (mntuws); Case Top For all next Moviecode into stk1 Where Title Contains 'ROOF'; Compute i/i2=1; type " Title Start Position of word ROOF" repeat stk1.Foccount Compute STK1(i).POS/I3 = POSIT(STK1(I).TITLE, 'ROOF'); Type " <STK1(i).Title <<STK1(I).pos" Compute i=i+1; endrepeat EndCase END
The following are sample values for MOVIECODE and values for the result of the POSIT function:
