Specify a variable name in the following format:
VARIABLE_NAME WIDTH [, PREC]
VARIABLE_NAME is a string, integer, or float variable, followed by its WIDTH specifier, and optionally, a PRECISION specifier.
WIDTH is a positive or negative integer constant specifying the number of columns in the field (including the decimal point and the PRECISION for floats). On input, the sign of the WIDTH specifier is ignored. On output, the sign of the WIDTH specifier indicates the justification of the value in the output field:
Sign |
Alignment in Output Field |
Blanks Appear |
Positive |
Right |
To left of value |
Negative |
Left |
To right of value |
PREC (PRECISION) is a positive integer constant specifying the number of digits to the right of the decimal point for a float variable. If no PRECISION is specified for a float variable in the record definition, zero is used. (PRECISION will be ignored if specified for either string or integer variables.)
