How to parse a numeric string without any delimiters?
Hi ,

I have a number say 12345001 which needs to be parsed. Its a number that has no delimiters.I have to read the last three digits and then the rest of digits irrespective of the total length of the number. The digits then have to be swapped and changed to a fixed length. The fillers to be inserted are X.

In short the input is 12345001 and the output needed is 001XX12345. The total length has to be 10.

Please suggest a solution which is performance oriented because the input has to be read from a file that would have around 50K records in it.

TIA.

plsxax

PLSXAX(3plplot) 						    PLplot API							   PLSXAX(3plplot)

NAME

       plsxax - Set x axis parameters

SYNOPSIS

       plsxax(digmax, digits)

DESCRIPTION

       Sets values of the digmax and digits flags for the x axis.  See the PLplot documentation for more information.

       Redacted form: plsxax(digmax, digits)

       This function is used in example 31.

ARGUMENTS

       digmax (PLINT, input)
	      Variable	to  set  the  maximum number of digits for the x axis.	If nonzero, the printed label will be switched to a floating point
	      representation when the number of digits exceeds digmax.

       digits (PLINT, input)
	      Field digits value.  Currently, changing its value here has no effect since it is set only  by  plbox(3plplot)  or  plbox3(3plplot).
	      However, the user may obtain its value after a call to either of these functions by calling plgxax(3plplot).
