Increment A string value by 1

(0) ShareShare
ReportReport
Posted on by Muhammad_Ali 353

Hi -

  I have a bit of a complex requirement (at least I believe so) . We have a string field as ACH#. The format of the string value is always the same like this "ACH-18-041, ACH-18-042, ACH-18-043".  My job is to read this string value for example  "ACH-18-043" and increment the last digit on the number "043" to "044". How can I achieve this with X++ code. ? Any help will be much appreciated.

I have to use x++ cant work with number sequence FW.

Regards

    Firstly,you can retrieve the last 3 digits by substring function

    msdn.microsoft.com/.../aa677836.aspx

    After that converts this string to integer with str2int function

    msdn.microsoft.com/.../aa845181.aspx

    Also you can check this thread to increment value

    Hi -

     I did manage to solve this by the solution below.  I do agree that substr() can also be used to work with this requirement.

      ACH = this.MTRA_getACHNumber(_projgrant);
       buffer = new TextBuffer();
       buffer.setText(ACH);

        if (ACH like "ACH*")
        {
            while (buffer.nextToken(0, '-'))
            {
                cnt++;
                if(cnt == 1)
                {
                    ACHstr =   buffer.token();
                }
                else if(cnt == 2)
                {
                    ACHYear =  buffer.token();
                    yearCode = substr(strFmt('%1', year(systemDateGet())), 3, 2);
                    if(ACHYear == yearCode)
                    {
                        ACHYear =  buffer.token();
                    }
                    else
                    {
                        if (ACHYear < yearCode)
                        {
                            ACHYear = yearCode;
                        }
                    }
                }
                else if(cnt == 3)
                {
                    ACHcode =  buffer.token();
                    if (ACHcode like "0*")
                    {
                        ACHcode = '0' ;
                    }
                    i = str2int(buffer.token());
                    i = i + 1 ;
                }
            }
               return ACHstr + '-' + ACHYear + '-' + ACHcode + int2str(i);
        }
        else
        {
              return this.MTRA_getACHNumber(_projGrant);
        }
