CALL — CALL macro
Format
CALL[ repeat-count] macro-name, parameter-value, ...;
Parameters
repeat-count:
number of times the macro is to be executed
macro-name:
name defined by a MCRO command
parameter-values:
values given to the dummy parameters in the macro definition
Function
The CALL command executes a macro previously defined by a MCRO command. The
macro may be executed any desired number of times by specifying a repeat count. Note
that the repeat count is not followed by a comma. If the repeat count is omitted, the
macro is executed once.
Only the first four characters of the macro name are significant. They must match the
first four characters of a macro name defined by a previous MCRO command.
A parameter value consists of the characters that occur between the delimiting commas,
excluding the commas. These parameters are substituted without change for the
corresponding dummy parameter in the macro definition, except that consecutive spaces
are compressed to a single space.
When a character-string parameter is enclosed in apostrophes or quotation marks, the
enclosed string together with the enclosing apostrophes or quotation marks is substituted
for the dummy parameter. In this case, consecutive spaces are not compressed.
If a CALL command has too few parameters, it is still valid. The macro is partially
executed; any commands in the macro body without appropriate parameters will be
ignored.
The CALL command, like other commands, is limited to 255 characters in length.
