IFROMC and CFROMI provide a simple, portable facility for storing character strings of 1-4 characters packed into integers.

Structure:

FUNCTION subprograms
User Entry Names: IFROMC, FROMI
External References: CHTOI, ITOCH

Usage:

    I=IFROMC('string')

stores in I a packed ASCII representation of the 4 leftmost characters of 'string'. If there are fewer than 4 characters, blanks are stored in the empty positions.

    CHARACTER*4 STRING
    ...
    STRING=CFROMI(I)

stores in STRING the four characters stored packed in I in their ASCII representation.
