Start 1

[JSutor]

When does a Start statement lock the record?? and when is it best to use the Start... No Lock??

 

[k5tm]

I am not aware of a COBOL implementation that locks on START. Which COBOL implementation are you using?

Cobol/400 on an AS/400

 

[fredericofonseca]

AS400/COBOL does not lock on START.

I can't think of a reason for START to lock. How can it, as it does not address a specific record, even START EQUAL does not

 

[JSutor]

Then why is there a start... No lock statement available??

 

[CobolKid]

The START statement logically positions a relative or indexed file for accessing records sequentially.

 

[fredericofonseca]

with COBOL/400 there is no such thing.

I should have told you I was talking about Cobol ILE I'm sorry about that!! There is a Start NO LOCK statement that is valid in Cobol ILE. But the question is since there is a Start NO LOCK option, at what point does a Start statement lock the record???

At least Microsoft COBOL and IBM COBOL [did] support it. Microsoft says: "[this syntax] is accepted by your COBOL system purely for compatibility with IBM 1.0 syntax and Microsoft V2.0 syntax".

START file-name [LOCK] [WAIT]

General Rules:
If you set the MS Compiler directive, the LOCK and WAIT clauses in the START statement are allowed and treated as documentary.
