help: before job subroutine dealing wtih hash file

[idocrm]

Gurus,
Can you please tell me what are some of the functions available
to open a hash file (with path), set column value for a particular key? (I think I can do this by developing a job, but I want to see if I can do this by using subroutine)
What I have is a hash file shared by several jobs. Since they run in different time schedule, I can't check the 'clear file before writing' option under 'Update action'.
Say my hash file columns look like the following:
key|count
and I have these entries
"one"|123
"two"|456
I want to write a subroutine to accept a 'key' parameter and hash file name (with path) so that I can set its count to an initial value.
My subroutine will be something like InitHashPerKey(hashFielName,key)
Any ideas are appreciated.

Use OpenPath statement to open the hashed file, ReadU or RecordLockU to lock the record for update, and Write to update (overwrite) the record.
Find all these statements in on-line help or in the BASIC manual.

Alternately, generate an SQL statement and execute it via DSExecute() function.
Shell = "UV"
Command = "INSERT INTO table (@ID,F1) VALUES ('one','123');"
Output = ""
Code = 0
Call DSExecute(Shell, Command, Output, Code)
If Code 0
Then
Call DSLogWarn("Error in hashed write.","MyRoutine")
End
