Back to Script Statements and Keywords (page 219).
Call
The call control statement calls a subroutine which must be defined by a sub statement. The syntax is:
callname ( [ paramlist ])
Where:
name is the name of the subroutine.
paramlist is a comma separated list of the actual parameters to be sent to the subroutine.
Each item in the list may be a field name, a variable or an arbitrary
expression.
The subroutine called by a call statement must be defined by a sub encountered earlier during script
execution.
Parameters are copied into the subroutine and, if the parameter in the call statement is a field name, copied
back out again upon exiting the subroutine.
Since the call statement is a control statement and as such is ended with either a semicolon or end-of-line, it
must not cross a line boundary.
Examples:
// Example 1
sub INCR (I,J)
I = I + 1
exit sub when I < 10
J = J + 1
end sub
call INCR (X,Y)
// Example 2 - List all QV related files on disk
sub DoDir (Root)
for each Ext in 'qvw', 'qvo', 'qvs', 'qvt', 'qvd'
for each File in filelist (Root&'\*.' &Ext)
Load '$(File)' as Name, FileSize( '$(File)' ) as
Size, FileTime( '$(File)' ) as FileTime
autogenerate 1;
next File
next Ext
for each Dir in dirlist (Root&'\*' )
call DoDir (Dir)
next Dir
end sub
call DoDir ('C:')
