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)

1 2 ... 7 8 9 10 11 12 13 14 15 16 17 ... 29 30
