Routine Description:
|
||
|
|
|
||
|
|
This routine converts an ASCII string to decimal and updates the
|
||
|
|
input pointer to point the last character of the number. The string is
|
||
|
|
parm of a descriptor.
|
||
|
|
|
||
|
|
Arguments:
|
||
|
|
|
||
|
|
Number - points to a LPDESC pointing to a number in ASCII format. The
|
||
|
|
pointer is updated to point to the next location after the number.
|
||
|
|
|
||
|
|
Return Value:
|
||
|
|
|
||
|
|
The decimal value of the string.
