INTEGER FUNCTION PRSNUM (STATUS, STDHMS, HLPSTR, LENHLP, DEFSTR,
X LENDEF, OPTION)
C$ (Parse - Number)
C$ Parse an integer number, leaving it in COMMON. The
C$ arguments are:
C$
C$ STATUS.........Parsing status value (and function value)
C$ returned; one of EOF, NOPABT, NOPHLP,
C$ NOPIFL, NOPNUL, NOPNUM, NOPRDX, NOPUNK,
C$ OKAY, OVRFLO, or REPARS. The help return,
C$ NOPHLP, is only given if an alternative
C$ parse is in progress. Otherwise, this
C$ routine loops until the user completes the
C$ input field with something other than the
C$ help character.
C$ STDHMS......... .TRUE. - issue standard help message.
C$ .FALSE. - suppress standard help message.
C$ HLPSTR(*)......Packed Hollerith help string.
C$ LENHLP.........Length of HLPSTR(*).
C$ DEFSTR(*)......Packed Hollerith default value string.
C$ LENDEF.........Length of DEFSTR(*).
C$ OPTION.........Integer option code. Set to RADIX+n for
C$ a number in radix n, where n is in the range
C$ 2..16. If an unsigned number is required,
C$ add UNSIGN to OPTION; plus and minus then
C$ become break characters.
