defined by the value of the configuration variable BC_STRING_MAX.

Message: valid array index is 0 through num
Cause: You specified an array index that was not in the range 0 to BC_DIM_MAX-1,
where BC_DIM_MAX is a configuration variable indicating the maximum num-
ber of elements that a bc array may have.
Action: Specify an array index in the indicated range.

Cause: You attempted to assign a value to the variable var that was not in the range
num1 to num2.

Message: warning: body of if/else statement is empty
Cause: You did not supply any statements for the body of an if or if/else construct.
bc only generates this message when you have specified the –i option.
Action: Make sure that this is what you intended. Check the DESCRIPTION section for
a discussion of bc syntax.
Message: warning: ’=-’ operator assumed
Cause: This version of bc permits the use of the old style assignment operators like =-
rather than -=. This can be ambiguous since a=-2 can mean a=-2or a
=-2.
Action: Use spaces to clarify the syntax of the expression.
