C DESCRIPTION:
|
||
|
|
C This routine strips leading and trailing blanks from a string. It
|
||
|
|
C does not modify or copy the string, but simply returns the
|
||
|
|
C location of the first and last non-blank characters. If the
|
||
|
|
C string is completely blank, ILEFT=LEN(STRING)+1 and IRIGHT=0 will
|
||
|
|
C be returned.
|
||
|
|
|
||
|
|
C FORMAL PARAMETERS:
|
||
|
|
C STRING CHARACTER Any character string.
|
||
|
|
C ILEFT INTEGER Position of first non-blank character.
|
||
|
|
C IRIGHT INTEGER Position of last non-blank character.
