Increases a positive number or decrease a negative number inside a string by one (1). 

NewString := INCSTR(String)

Parameters

String

Type: Text constant or code

The string that you want to increase or decrease.

Property Value/Return Value

Type: Text constant or code

The result after increasing or decreasing String.

Remarks

If String contains more than one number, then only the number closest to the end of the string is changed. For example, 'A10B20' is changed to 'A10B21' and 'a12b12c' to 'a12b13c'.

If String contains a negative number, then it is decreased by one. For example, '-55' is changed to '-56'.

Zero (0) is considered a positive number. Therefore, it is increased it by one. For example, 'A0' is changed to 'A1'.

When String contains a number such as 99, it is increased to 100 and the length of the output string is: LEN(String) + 1. For example, 'a12b99c' is changed to 'a12b100c'.

If String does not contain any number, the output string is an empty string. For example, 'aaa' is changed to ''.

INCSTR only increments integer numbers within strings, not decimals. For example, if you call INCSTR on the string a99.99b then the result is a99.100b.

Example

This example requires that you create the following variables and text constants in the C/AL Globals window.

Variable name DataType Length

Account

Text

60

NegAccount

Text

60

EmptyAccount

Text

60

MyAccount

Text

60

ResultAccount

Text

60

ResultNegAccount

Text

60

ResultEmptyAccount

Text

60

ResultMyAccount

Text

60

Text constant ENU value

Text000

Account no. 99 does not balance.

Text001

Account no. 2342 shows a total of $-452.

Text002

My bank account is empty.

Text003

My bank account shows a total of $0.

Text004

The text strings before INCSTR is called:\%1\%2\%3\%4

Text005

The text strings after INCSTR is called:\%1\%2\%3\%5

 Copy Code
Account := Text000;
NegAccount := Text001;
EmptyAccount := Text002;
MyAccount := Text003;
MESSAGE(Text004, Account, NegAccount, EmptyAccount, MyAccount);
ResultAccount := INCSTR(Account);
ResultNegAccount := INCSTR(NegAccount);
ResultEmptyAccount := INCSTR(EmptyAccount);
ResultMyAccount := INCSTR(MyAccount);
MESSAGE(Text005, ResultAccount, ResultNegAccount, ResultEmptyAccount, ResultMyAccount);

The first message displays the following:

The text strings before INCSTR is called:

Account no. 99 does not balance.

Account no. 2342 shows a total of $ -452.

My bank account is empty.

My bank account shows a total of $ 0.

The second message displays the following:

The text strings after INCSTR has been called:

Account no. 100 does not balance.

Account no. 2342 shows a total of $ -453.

My bank account shows a total of $ 1.

The example shows that if the string contains more than one number, only the last number is changed. Furthermore, positive numbers and zero are increased and negative numbers are decreased. Finally, if there are no numbers in the string, then an empty string is returned.
