DEFtype
• DEFINT letter or range
• DEFSNG letter or range
• DEFDBL letter or range
• DEFSTR letter or range
Examples:
DEFINT A,I,N
All variables beginning with A, I or N will be treated as integers. For example, Al, AA, 13 and NN will be
integer variables. However, A1#, AA#, I3# would still be double precision variables, because of the type
declaration characters, which always override DEF statements.
DEFINT I-N
Causes variables beginning with I, J, K, L, M or N to be treated as integer variables.
DEFINT may be placed anywhere in a program, but it is normally placed at the beginning of a program.
CLEAR
Deletes all variables values and types, and array dimensions. Clears any DEFtypes .
DIM name (dim1, dim2, …, dimK)
Lets you set the "depth" (number of elements allowed per dimension) of an array or list of arrays. If no DIM
statement is used, a depth of 11 (subscripts 0-10) is allowed for each dimension of each array used.
Example:
DIM A(5),B(2,3),C$(20)
